Marvel Rivals Stuck on the Loading Screen — Here's the Fix

An infinite loading screen in Marvel Rivals is almost always one of two things: a corrupted shader/pipeline cache that stalls the Unreal Engine load, or a network handshake that never completes so the match can't finish loading. The fixes below are ordered — start with the cache and file verify, then move to the network steps if it still hangs.

Marvel Rivals stuck at 99% — real causes

#1 cause of 99%
Slow HDD — move the game to an SSD (Steam: Properties -> Installed Files -> Move install folder)

Run game + launcher as administrator; update GPU drivers (driver conflict is common even if not outdated)

Error codes

Infinite loading before a match The Unreal Engine load stalls building or reading the shader/pipeline cache.

Cause: A corrupted DirectX shader cache or a mismatched cache after a game/GPU-driver update makes the engine loop while compiling shaders, so the loading bar never completes.

Fix:
  1. Clear the DirectX shader cache: Disk Cleanup > tick "DirectX Shader Cache" > OK, then relaunch.
  2. Verify game files (Steam: Properties > Installed Files > Verify integrity; Epic: ... > Manage > Verify).
  3. Do a clean GPU driver install (DDU, then latest NVIDIA/AMD driver) if it started after a driver update.
  4. Delete the game's local cache/config folder in %LOCALAPPDATA% and let it rebuild on next launch.
Stuck loading into a match / lobby The client loads assets but never syncs with the match server.

Cause: A NAT/firewall block or packet loss stops the peer/match handshake, so all players show as loading and the match never starts.

Fix:
  1. Allow Marvel Rivals through Windows Firewall (Private and Public).
  2. Flush DNS (`ipconfig /flushdns`) and switch to 1.1.1.1 or 8.8.8.8.
  3. Set NAT type to Open (enable UPnP or forward the game ports) on console/PC.
  4. Use wired Ethernet to remove Wi-Fi packet loss during the sync.

Fixes that work for most Marvel Rivals errors

  1. Restart the game fully (not just Continue) — a stale session is the fastest thing to rule out.
  2. Check the official Marvel Rivals server status/socials for a live outage or maintenance before troubleshooting locally.
  3. Disable Steam/Discord/GeForce overlays that can hook the loader and stall it.
  4. Turn off any VPN or proxy that can break the match handshake.
  5. Lower graphics to Medium and disable ray tracing on first launch after an update while the shader cache rebuilds.
  6. Update Windows and your GPU driver — an out-of-date DirectX runtime can loop shader compilation.

FAQ

Why does Marvel Rivals load forever only after an update?

Updates invalidate the shader cache and can outdate your GPU driver, so the engine loops rebuilding shaders. Clearing the DirectX Shader Cache and updating the driver fixes it.

Is it my internet or the game?

If you hang before the character/menu it's usually the shader cache; if you hang loading into a match with other players it's the network handshake — fix DNS/firewall/NAT.

Does verifying files delete my settings?

No. Verifying only replaces corrupted or missing game files; your account settings and progress are stored server-side and locally in config, which is untouched.

Should I reinstall?

Reinstalling is a last resort. Clear the shader cache, verify files and fix the network path first — those solve the large majority of infinite-loading cases.
