Also have this issue - can’t do anything, reinstalling doesn’t help. Only way was to nuke all settings from AppData/Roaming. Now I need to spend time setting up my IDE from scratch instead of working… Tbh the issues are becoming a bit too much recently

Facing same issue. cursor –disable gpu did not work for me.
i am on windows 11.

This happens to only one specific project which doesn’t open.

I see this error in my logs when i open the directory
ERR illegalState - setting UNKNOWN service instance: Error: illegalState - setting UNKNOWN service instance.

My cursor version is 2.4.27

Deleting %APPDATA%\Cursor\User\workspaceStorage\ worked for me!

I’m sharing the following in the hope that it will help others who experience the same issue I did. I am on Windows 11 with WSL.

I encountered an issue where Cursor would open as a blank gray box (no panels or menu) for one specific workspace folder, while other folders worked fine.

How I fixed it:

  1. Ran cursor --verbose from the command line to capture diagnostic output

  2. Pasted the first “1,000” lines of the verbose output into Claude for analysis

  3. Claude identified the corrupted workspace ID: f132ea05bf4d88c65c5635caad7ca7b0

  4. I opened %APPDATA%\Cursor\User\workspaceStorage in Windows Explorer

  5. Renamed the folder matching that workspace ID (or I could have just deleted it entirely)

  6. Relaunched Cursor - it now opens correctly

The issue was workspace-specific corruption in Cursor’s storage. Removing the corrupted workspace folder forces Cursor to rebuild its state for that folder.
