Step-by-Step Troubleshooting Microsoft Teams "X Error" Startup Crash

Start simple and escalate if needed. Test Teams after each step.

  2. πŸ‘‰ Clear Teams Cache
    Quit Teams completely. Navigate to %appdata%\Microsoft\Teams in File Explorer (paste and hit Enter). Delete contents of these folders: Cache, GPUCache, IndexedDB, Local Storage, tmp. Relaunch Teams – boom, fresh start!
