Resolving “Uncaught Exception” Error During Code Studio Auto Update

This article explains how to resolve the “Uncaught Exception” error that may occur when CodeStudio is launched during its automatic update process.

Why This Issue Occurs

• Users may encounter an Uncaught Exception error if CodeStudio is opened before the automatic update process has fully completed.
• This happens because essential files are still being modified, leading to temporary conflicts.
• The error can prevent CodeStudio from starting and usually requires either waiting for the update to finish or performing a clean reinstallation if the issue persists.

Resolution Steps

Quick Fix

1. Close the error dialog.
2. Wait a few minutes for the automatic update to complete in the background.
3. Relaunch CodeStudio. The application should start successfully with the latest version.

If the Issue Persists (Clean Reinstallation)

Step 1: Uninstall CodeStudio

Windows

• Open Windows Settings → Apps.
• Find and select Syncfusion CodeStudio.
• Click Uninstall and follow the prompts.

• Rightclick and select Move to Trash / Move to Bin.

Step 2: Remove Cache Files

Step 3: Reinstall CodeStudio

Verification
To confirm the issue is resolved:
