Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the detailed report.

I see the “Not responding” screen when using CMD+K Edit. There are a few similar reports on Windows with version 2.2..

For diagnostics, could you check:

  1. Extensions: CMD+Shift+P > Developer: Open Extension Monitor - do any extensions show high CPU/memory? Try launching Cursor with cursor --disable-extensions from the command line.

  2. Process Explorer: CMD+Shift+P > Developer: Open Process Explorer - what consumes resources at the moment of the freeze?

  3. Console logs: Help > Toggle Developer Tools > Console tab - reproduce the CMD+K Edit issue and share any errors.

Also please provide:

  • Project size/number of files
  • Which file you’re editing when the freeze happens
  • The list of installed extensions

This will help us identify the pattern.

3

It seems cmd+shift+p does not have Developer: Open Extension Monitor command, how could I see extension CPU/Memory usage?

4

Oh, got it. You need to enable it first.
The “Developer: Open Extension Monitor” command appears only after you turn on the flag:

  1. Open Settings Ctrl+, > Application > Experimental
  2. Enable “Extension Monitor Enabled”
  3. Restart Cursor
  4. Then run CMD+Shift+P > Developer: Open Extension Monitor and check CPU/Memory for extensions
5

  1. All user extensions show 0 usage and show 98.64 % ExtHost 2.7& CPU 258KB Memory, anysphere.cursor-always-local accounts for 1.36% ext host and 0 others; launching cursor with extensions disabled does not prevent it from not responding.

  2. while freezing, the trigger window CPU consumption 1% → 5%, Memroy rise from 50MB to about 5GB in less than 10s then clear back to 30MB then repeat the rise progress for about 5 times, then rise slowly in a about 5MB/s rate

 the system memory is sufficient enough

Thanks for the detailed diagnostics, it’s very helpful.

A memory spike from 50 MB to 5 GB and the tokenizeToString error is a known issue on Windows 2.2.x, and the team is working on a fix.

Please check one setting:

  1. Open Settings (JSON) via Ctrl+Shift+P > “Preferences: Open Settings (JSON)”
  2. Find "workbench.editor.showTabs" - if the value is "single", change it to "multiple" or remove this line

Also clarify:

  • Which Windows Update version is installed? (Settings > Windows Update > Update history) - there were reports that rolling back KB5068861 helped

If the showTabs setting didn’t help, try a full cache cleanup:

  1. Close Cursor
  2. Delete the folders %APPDATA%\Cursor and %LOCALAPPDATA%\cursor-updater
  3. Restart
7

Thanks, the showTabs setting solved this problem
the current windows version is KB5067931 btw
