Frequent Freezing and Errors in Course Extensions

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m writing to report an ongoing issue with the course extensions that are constantly freezing and stopping. For example, when I use Combined Coding along with other extensions during the course, it repeatedly freezes, shows unexplained internet errors, and becomes unusable. This problem started recently—everything was working fine last week. I’m certain this isn’t related to my machine, as I’ve tested it thoroughly.

Are the developers aware of this backend bug in the course platform? Is there an estimated timeline for a fix? This is severely impacting my progress.

Hey, thanks for the report. To pinpoint the issue, please try these diagnostic steps:

Find the problematic extension:

  • Click “Start Extension Bisect” to systematically identify which extension is causing the freeze
  • Or check Settings > Application > Experimental > Extension Monitor to see CPU/RAM usage per extension

Test without extensions:

  • Run Cursor with cursor --disable-extensions from the command line
  • Does the freezing still occur?

This will help us see if it’s an extension conflict. Let me know what you find.
