3. Delete all folders inside (e.g., Cache, GPUCache, IndexedDB).
4. Restart Teams. Boom – fresh start! 🚀

3️⃣ Disable Hardware Acceleration

Graphics glitches trigger crashes. Disable it:

1. In Teams: Settings → General → Turn off Disable GPU hardware acceleration.
2. Restart Teams.

This fix resolves Hard Errors on NVIDIA/AMD/Intel GPUs in recent builds.

4️⃣ Reinstall Microsoft Teams (Clean Slate)

If cache clears fail, nuke and reinstall:

5️⃣ Update Windows and Drivers

• Windows Update: Settings → Update & Security → Check for updates.
• Graphics drivers: Use Device Manager or official tools (GeForce Experience, AMD Software).
• Run SFC /scannow in admin Command Prompt: sfc /scannow then DISM /Online /Cleanup-Image /RestoreHealth.

6️⃣ Advanced Fixes for Stubborn Errors

Still crashing? Try these:

• Run as Admin: Right-click Teams → Run as administrator (permanent via Properties → Compatibility).
• Antivirus Check: Add Teams folders to exclusions (e.g., Windows Defender → Virus & threat protection → Exclusions).
• Event Viewer: Search for error details (Win + R → eventvwr) to pinpoint modules like ntdll.dll.
• Reset Teams via PowerShell: Get-AppxPackage *Teams* | Remove-AppxPackage (for MS Store version).

Pro Tip: If on a corporate PC, contact IT – Group Policies might block fixes. 💡
