Сan't install extensions

I can’t install extensions for Cursor. An error appears when trying to install
err1

Also these are the errors in the console: “Failed to load resource: the server responded with a status of 412 ()”. I can’t provide a photo because I’m a new user.

I tried to remove Cursor and install it again, but it retains the old settings

Hello! Can you confirm whether this is still happening for you?

yes, I still can’t install extensions
