🔥 Top 7 Step-by-Step Fixes for Microsoft Teams JavaScript Error

1️⃣ Clear Teams Cache and App Data (Quickest First Step)

The #1 culprit? Stale cache. Here's how to wipe it clean:

1. Quit Microsoft Teams completely (use Task Manager on Windows or Activity Monitor on Mac).
2. Press Windows + R (Windows) or go to Finder (Mac), then navigate to:
   %appdata%\Microsoft\Teams (Win) or ~/Library/Application Support/Microsoft/Teams (Mac).
3. Delete folders like Cache, blob_storage, databases, IndexedDB, Local Storage, tmp.
4. Restart Teams. Boom—error gone for 80% of users! ✨

2️⃣ Update or Reinstall Microsoft Teams Desktop App

Ensure you're on the latest version:

1. Open Teams > Profile icon > Check for updates.
2. If stuck, download fresh installer from official Microsoft site.
3. Uninstall old version via Settings > Apps (Win) or drag to Trash (Mac), then reinstall.

Pro Tip: Opt for the new Teams version—it's more stable against JS errors.

3️⃣ Disable Hardware Acceleration

Graphics glitches trigger JS failures:

1. In Teams, go to Settings > General.
2. Toggle off Disable GPU hardware acceleration (wait, enable the disable option? Yes!).
3. Restart app. Test in a meeting—smoother sailing! ⚡

4️⃣ Run as Administrator & Check Permissions
