Hey, thanks for the report. This is a known issue with the extension host, and the team is aware and tracking it.

First, try a few things:

1. Start Cursor without extensions from the terminal:

   cursor --disable-extensions
   

   If it works, one of your extensions is causing a conflict.

2. Check Process Explorer (Cmd + Shift + P > “Developer: Open Process Explorer”) and see if there’s a stuck extensionHost.

3. Clear the cache and restart:

   • Fully quit Cursor
   • Delete ~/Library/Application Support/Cursor/CachedExtensionVSIXs
   • Launch it again

If nothing helps, a temporary workaround is to downgrade to the previous version. At Download · Cursor, there’s a “Previous versions” section at the bottom.

Also, can you share your list of installed extensions, and whether you have any MCP servers in your config?

In my case ot was a problem with Java extensions because I live in Russia and Orcale banned my IP

[jack99]

me too, nothing works

I encountered the same issue and wanted to share how I got it working.

In my case, I went to Cursor settings, selected the Network option on the left menu, and chose Run Diagnostic. Although I don’t recall the specific categories that failed, the results indicated an issue with HTTP compatibility.

I switched the HTTP Compatibility Mode from HTTP/2 to HTTP/1.1, which resolved the problem. I noticed that this issue specifically occurred while I was connected to a VPN; when I was on the office/corporate network, everything worked normally. Please note that I had to switch back to HTTP/2 while on the corporate network, as HTTP/1.1 did not work in that environment.

Hope this works for you as well.
