I can’t install extensions for Cursor. An error appears when trying to install ![err1](https://us1.discourse-cdn.com/cursor1/original/2X/3/3f518c3b1a176e8e19d91eb21e423f93a779b0ba.png) 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 ---

This issue still remains for me with a fresh Cursor download (cursor-0.45.14x86\_64.AppImage). [This recommended workaround](https://forum.cursor.com/t/tip-downloading-vsix-extensions-now-that-ms-removed-the-option-in-marketplace/50646) doesn’t work since there is no menu entry like “Download VSIX” when I click the gear icon (nor somewhere). I tried with PHP Intelephense which is important for me. So I’m afraid I have to switch back to VS Code in order to keep my productivity as it was so far…
