3️⃣ Step 3: Update Everything—Teams, Windows, and Drivers

Outdated software = crash city. Quick checks:

• Teams: Profile > Check for updates.
• Windows: Settings > Update & Security > Windows Update > Check now.
• Drivers: Right-click Start > Device Manager > Update Display adapters/Network adapters.

For NVIDIA/AMD: Download latest from NVIDIA or AMD sites.

4️⃣ Step 4: Reinstall or Reset Teams (Nuclear Option—99% Success)

If crashes persist:

1. Uninstall via Settings > Apps > Microsoft Teams > Uninstall.
2. Download fresh installer from official site.
3. Or reset: Settings > Apps > Teams > Advanced > Reset.

Test in Safe Mode first: Restart PC holding Shift > Troubleshoot > Advanced > Startup Settings > Safe Mode. If no error, a third-party app is guilty—uninstall recent ones.
