@lgutierrezr Do you see anything in the Output > Python logs? or the Developer Tools logs (Help > Toggle Developer Tools)

"workbench.html:1 Access to fetch at 'https://www.vscode-unpkg.net/_gallery/ms-python/python/latest' from origin 'vscode-file://vscode-app' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status."

That looks like it is VS Code core trying to find the latest version of python extension. That error is not originating from the python extension. If that is the only issue, see if you can manually update python extension or disable update and see if that works.

I will try to update manually, I will let you know if the problem persists.

I reinstalled the extensions, upgraded to the latest version of VScode. upgraded from python 3.11.7 to 3.13.1 and had to install “Microsoft Visual C++ 14.0 which was in Microsoft C++ Build Tools” from VS 2022. Now VSCode and its extensions are without performance issues.

PS: It's a bit weird that in this update I had to do it manually. But everything is back to normal.

Thank you @karthiknadig
