I would recommend opening an issue on the plutus issue tracker for this kind of case: https://github.com/input-output-hk/plutus/issues

Might be this? "If you're using Windows and WSL, make sure the plutus repo clone is located in the WSL filesystem" (https://stackoverflow.com/questions/68276780/plutus-playground-client-cannot-run)

No, it is located in the WSL filesystem. I'm planning to switch to ubuntu

I recommend installing Virtual Box and using NixOS or just installing NixOS on a flash drive.
