My VS Code suddenly unable to run all sorts of files (html, css, javascript, python) with a pop-up window “Code language is not supported or defined”. It worked just fine before I uninstalled python3 and cleared all python3 related variables in the terminal. The thing is the python3 files are still in my MAC System, but the VS Code path is not working like it used to. Perhaps I accidentally deleted some software. Anyone could provide guidance and a solution, please? Thank you.

I reinstall VS Code 4 times, and I applied the solution suggested in VS Code Official website and ChatGPT but the issue still persists. I am considering of having my Mac Reboot at Computer shop cause i am out of solutions now.
