The issue occurs consistently when opening the particular project in an IDE instance that already has other projects open, causing the UI to freeze. However, the same project opens and works without any problems if it is the only project opened in the IDE.
1. File | Invalidate Caches | Enable Clear file system cache and Local History option | Invalidate and Restart
2. File | Repair IDE
3. Settings | Plugins | ⚙ | Disable all downloaded plugins (For issue isolation purpose only)
4. Settings/Preferences → Editor → General → Editor Tabs → uncheck “Show file icon” and restart the IDE
If the issue persists, please collect the zipped log folder from "Help | Collect Logs and Diagnostic Data" and let us know if you open the second project in the a new window or in the current window.
Thank you for your guidance. I have performed the troubleshooting steps, and here are the results:
The critical finding is that disabling the "Show file icon" setting (Step 4) successfully resolves the unresponsiveness issue.

Delete `C:\Users\userName\AppData\Roaming\JetBrains\IntelliJIdea2025.3\options\recentProjects.xml`.
restart IDEA to disable “Show file icon”.
and then restore the deleted file.

You can fix this by uninstalling the Maven plugin from IDEA.
