Blank window when opening specific project; fixed by deleting workspaceStorage (chat history lost)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I open a specific QGIS plugin project folder in Cursor, the entire window becomes blank (white). Other projects, including similar QGIS plugin projects, open normally. Deleting the corresponding workspaceStorage folder for that project fixes the issue, but all previous chat history for that workspace is lost. I work with Hebrew text (UI and/or code/comments), which might be related.
Steps to Reproduce:
OS: Windows 10
In Cursor, go to File → Open Folder…
Select the folder:
C:\Users\Oren Luzon\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\polygon_analyzer
Cursor opens a new window for this folder.
The window is completely white/blank, no UI elements or files are visible.
Close Cursor.
In File Explorer, go to:
C:\Users\Oren Luzon\AppData\Roaming\Cursor\User\workspaceStorage
Delete (or rename) the folder:
ba9f204ff8a56aafc808a00a40e66f08c (workspace folder associated with polygon_analyzer).
Open Cursor again and use File → Open Folder… on the same polygon_analyzer folder.
Expected Behavior:
The project opens normally, with file explorer and editor visible. Existing chat history for that workspace remains available.
Actual Behavior:
Before deleting workspaceStorage: opening the polygon_analyzer folder results in a completely blank white window.
After deleting the workspace’s workspaceStorage folder: the project opens correctly, but all previous Cursor chat history for that project is lost.
Environment:
OS: Windows 10 (Hebrew locale)
Project: QGIS plugin at
C:\Users\Oren Luzon\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\polygon_analyzer
Other projects (including another QGIS plugin project) open fine in Cursor.
I frequently work with Hebrew text (in code/comments and/or UI).
Additional Notes:
This suggests that some corrupted state in the per‑workspace workspaceStorage for this project can cause Cursor to render a blank window, and that clearing workspaceStorage fixes the UI but discards chat/session history.

Steps to Reproduce

cannot reliably reproduce the bug now because deleting the workspaceStorage folder fixed it, but this is exactly what happened the first time:

  1. On Windows 10 (Hebrew locale), open Cursor.
  2. From the top menu, choose: File → Open Folder…
  3. Select the folder:
    C:\Users\Oren Luzon\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\polygon_analyzer
  4. Cursor opens a new window for this folder.
  5. The window is completely blank/white: no sidebar, no editor, only a white background.
  6. Close Cursor.
  7. In File Explorer, go to:
    C:\Users\Oren Luzon\AppData\Roaming\Cursor\User\workspaceStorage
  8. Delete the workspace folder that corresponds to this project.
  9. Open Cursor again and use File → Open Folder… on the same polygon_analyzer folder.
  10. Now the project opens normally, but all previous chat history for this workspace is gone.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This is a known issue: a corrupted workspace layout state, usually caused by the “Open Chat as Editor” feature. The team is aware.

For next time: if it happens again, you don’t need to delete the whole workspaceStorage folder. You can delete one key from the database and keep your chat history:

  1. Find the state.vscdb file in your workspace folder:
    C:\Users\Oren Luzon\AppData\Roaming\Cursor\User\workspaceStorage\<workspace-id>\state.vscdb

  2. Open it with any SQLite client (for example, DB Browser for SQLite) and run:

    DELETE FROM ItemTable WHERE key = 'cursor/editorLayout.auxiliaryBarVisible';
    
  3. Restart Cursor. Your project should open normally, and your chat history will still be there.

Also, for now it’s better to avoid “Open Chat as Editor”, since it can corrupt the workspace state again.
