I just started to get this error today.

In researching, I have tried all suggestions:

  • Removing all extensions
  • Removing the workspace storagecache

Any suggestions?

Weird can you share your ā€œAbout Cursorā€, it should have a similar version on early access

Did you wait for version to download and then restart cursor after switching?

I just switched back to nightly, it seems like they already patched it.
