Lethal Company crashed — probably right when things were getting scary. This Unity-based game is indie and still in early access, so crashes happen. Here's how to fix them.
Fix it:
- If you're using mods (BepInEx, r2modman, Thunderstore), this is almost certainly the cause. After a Lethal Company update, ALL mods need to be updated too. Disable all mods and test
- Update your mods: open r2modman or Thunderstore Mod Manager, check for updates on every mod. Outdated mods crash the game constantly
- If you recently installed BepInEx manually, make sure it's the correct version (x64 for most people). A wrong BepInEx version crashes on launch
- Verify game files on Steam: right-click > Properties > Installed Files > Verify Integrity
- If the crash only happens in multiplayer, the HOST needs stable internet. If the host has bad connection, everyone crashes
- Delete the BepInEx folder in Lethal Company's install directory for a clean mod slate, then verify game files
- Make sure your GPU driver is up to date — even for a simple-looking game, Unity still needs proper GPU drivers
- Lower resolution if the game struggles — some custom moons and modded content are poorly optimized
- Check the Lethal Company modding Discord for known crash-causing mod combinations
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
