Hey, I see this is a continuation of your previous thread The problem "Extension host terminated unexpectedly 3 times within the last 5 minutes" remain. Sadly, the cursor-socket fix from 2.6.18 didn’t fully make it into the latest builds, so there was a regression.
The root cause is the same: the out/ folder is missing inside cursor-socket. Please try the same workaround again like last time. Open Command Prompt as Administrator:
cd "%LOCALAPPDATA%\Programs\cursor\resources\app\extensions\cursor-socket"
xcopy dist out\ /E /I
If your install path is C:\Program Files\cursor, use this instead:
cd "C:\Program Files\cursor\resources\app\extensions\cursor-socket"
xcopy dist out\ /E /I
Then restart Cursor.
If Extension Host still crashes after that, also try this:
- Open Cursor Settings (not VS Code settings) > Indexing & Docs
- Turn off Index Repositories for Instant Grep (BETA)
- Restart Cursor
This combo helped other users on 2.6.21: Cursor Extension Host crashes repeatedly && cursor-socket extension is malformed - #11 by Thms.
Note: you’ll need to re-run xcopy after every Cursor update until this is fully fixed. The team knows about the regression, and your report helps with prioritization.
Let me know if it works this time.
