Hey, thanks for the report. Can you check a couple things:

  1. Is Cursor Tab enabled? Open Cursor Settings > Tab and make sure “Cursor Tab” is turned on. Also check the icon in the status bar at the bottom right. Click it and make sure Tab isn’t paused and isn’t disabled for .tsx files.

  2. Network diagnostics: Cursor Settings > Network > Run Diagnostics. If you see any errors, send a screenshot here.

  3. Try disabling HTTP/2: App settings Ctrl + , > search for “HTTP/2” > turn on “Disable HTTP/2” > restart Cursor.

  4. Extension conflict: Run cursor --disable-extensions from the command line and see if Tab works. If it does, re-enable extensions one by one to find the one causing it.

  5. Quick workaround: Ctrl + Shift + P > Developer: Reload Window. This helped other Windows users with similar Tab issues.

Let me know.
