Marvel Rivals Anti-Cheat Error Fix (Won't Launch)
Published
On this page
If Marvel Rivals won’t launch or shows an anti-cheat error, the fix is almost always a full cold restart plus launching Steam as administrator — Marvel Rivals’ NetEase kernel anti-cheat only initializes cleanly on a fresh Windows boot. The one exception is the message “The anti-cheat system is currently inactive,” which is a NetEase server problem, not your PC. Work the fixes below in order.
First: which error do you have?
Marvel Rivals anti-cheat problems split into two completely different causes. Fixing the wrong one wastes your time.
| What you see | Cause | What to do |
|---|---|---|
| ”The anti-cheat system is currently inactive. Please review server configuration” | NetEase’s anti-cheat service is down (server-side) | Nothing local helps — check status channels and wait |
| Game silently closes, black screen, or “anti-cheat failed to initialize” on launch | Client-side: the kernel driver didn’t load on your PC | Work Fixes 1–5 below |
If everyone is seeing “currently inactive” at the same time, it’s a server outage — you can confirm on the Marvel Rivals Steam discussions or the official Discord. Don’t reinstall anything; it will come back on its own.
Fix 1 — Do a full cold restart (not sleep, not hibernate)
Marvel Rivals uses a kernel-level anti-cheat that loads its driver during a complete Windows boot cycle. Resuming from sleep or hibernate does not reload it, which is the single most common reason the game fails to launch after your PC has been on for a while.
- Save your work and choose Start → Power → Restart (Restart, specifically — a full shutdown from sleep can skip the cold boot on Windows Fast Startup systems).
- Let Windows fully load before opening Steam.
- Launch Marvel Rivals.
If it launches after a restart but breaks again next session, disable Fast Startup (Control Panel → Power Options → Choose what the power buttons do → uncheck “Turn on fast startup”) so every boot is a true cold boot.
Fix 2 — Launch Steam and the game as administrator
The anti-cheat driver needs elevated permissions to install and start. If Steam is running without them, initialization can fail.
- Fully close Steam (right-click the tray icon → Exit).
- Right-click the Steam shortcut → Run as administrator.
- Launch Marvel Rivals from there.
To make it permanent: right-click steam.exe → Properties → Compatibility → check Run this program as an administrator.
Also make sure you are not closing the launcher after the game starts — if the launcher has an “Exit launcher when the game starts” option, uncheck it, or minimize it to the system tray instead of closing it.
Fix 3 — Verify the game files (this repairs the anti-cheat)
Marvel Rivals’ anti-cheat lives inside the game install. A corrupt or missing anti-cheat file is repaired by verifying, not by any external tool.
- In Steam, right-click Marvel Rivals → Properties.
- Go to Installed Files → Verify integrity of game files.
- Let it re-download any damaged files, then restart your PC and launch again.
⚠️ Do not download “Marvel Rivals anti-cheat repair tool” executables. There is no official one — the GitHub repos and sites advertising a “direct patch installer” for the anti-cheat are almost always malware or info-stealers. The only legitimate repair is Steam’s built-in file verification above. This is the same trap that surrounds every kernel anti-cheat; see is kernel-level anti-cheat safe? for why these downloads are dangerous.
Fix 4 — Temporarily disable third-party antivirus
Aggressive third-party antivirus (and some “game booster” tools) can quarantine or block the anti-cheat driver as it loads. Windows Defender is usually fine, but third-party suites are a common culprit.
- Temporarily disable your third-party antivirus, or add the Marvel Rivals install folder and its anti-cheat executable to its exclusion list.
- Launch the game to test, then re-enable protection. If this fixes it, keep the exclusion rather than leaving antivirus off.
Fix 5 — Update Windows and your GPU driver, then reinstall the anti-cheat
If the first four fixes fail:
- Install pending Windows Updates — kernel anti-cheat is sensitive to out-of-date system components.
- Clean-install your GPU driver (a broken driver can crash the game right as anti-cheat hands off rendering) — see how to clean-install GPU drivers with DDU.
- As a last resort, reinstall Marvel Rivals so the anti-cheat is written fresh. Because it ships with the game, a clean reinstall is the real “repair tool.”
Still broken? Rule out the wider crash
If Marvel Rivals gets past anti-cheat and then crashes mid-match, it’s no longer an anti-cheat problem — treat it as a GPU or stability crash. See DXGI_ERROR_DEVICE_HUNG for GPU-timeout crashes and the Marvel Rivals stuttering fix for frame-time hitches.

Frequently asked questions
What anti-cheat does Marvel Rivals use?
Marvel Rivals uses NetEase's proprietary kernel-level anti-cheat, which loads a driver during a full Windows boot and initializes before the game process starts. If anything blocks that initialization — a missed cold restart, an antivirus, or a launcher that closed too early — the game silently fails to launch or throws an anti-cheat error. Unlike Valorant or Battlefield 6, Marvel Rivals does not require Secure Boot or TPM 2.0.
What does 'The anti-cheat system is currently inactive' mean in Marvel Rivals?
That specific message is usually a server-side problem on NetEase's end, not your PC. When the anti-cheat service is down or between maintenance windows, every player sees 'anti-cheat is currently inactive' and no local fix will help — check the official Marvel Rivals status channels and wait it out. If only you see launch errors while others are playing, it is a client-side problem and the fixes below apply.
How do I fix Marvel Rivals not launching because of anti-cheat?
Do a full cold restart of your PC (not sleep or hibernate resume), because the kernel anti-cheat driver only loads cleanly on a fresh boot. Then launch Steam or the launcher as administrator, verify the game files, and temporarily disable third-party antivirus. These four steps clear the large majority of Marvel Rivals anti-cheat launch failures.
Are Marvel Rivals anti-cheat repair tools safe to download?
No. There is no official third-party 'Marvel Rivals anti-cheat repair tool.' The downloads and GitHub repos advertising one are almost always malware or information stealers — Marvel Rivals' anti-cheat ships inside the game itself and is repaired by verifying the game files, not by an external patch. Never run an executable that promises to fix anti-cheat; use the built-in file verification instead.
Does Marvel Rivals require Secure Boot or TPM 2.0?
No. Marvel Rivals' NetEase anti-cheat is kernel-level but does not mandate Secure Boot or TPM 2.0, unlike Valorant's Vanguard or Battlefield 6's Javelin. You do not need to change BIOS security settings to play — if a guide tells you to enable Secure Boot for Marvel Rivals, it is copying advice from a different game.
