Hey, thanks for the report. This is a known issue with the extension host.

A couple things to try:

  1. Start Cursor with extensions disabled. From a terminal: cursor --disable-extensions
  2. If that helps, it means some extension is conflicting. Enable them one by one to find the one causing it.
  3. If it doesn’t help, try resetting the extension state:
    • Close Cursor
    • Rename the folder: mv ~/.cursor/extensions ~/.cursor/extensions.bak
    • Start Cursor again

You can also try rolling back to version 2.4.9. It’s stable. Here’s a direct link for Linux x64 .deb: http://downloads.cursor.com/production/4119c25a8bbcda34554ee91403218e9964bfa88a/linux/x64/deb/amd64/deb/cursor_2.4.9_amd64.deb

Let me know which option works, or if none do, and we’ll dig further.
