Does anyone else have this issue? For reference check this screenshot: 
PIP is also up to date and I already tried reinstalling it but it didn’t work neither. I’m using VS Code. It also worked just fine yesterday but today it didn’t anymore for some reason.

Answer
Your mss package is installed locally, but you are using a virtual environment to run code.
Two solutions:
1. Switch the interpreter to the local interpreter, which is the c:UsersAnwenderAppDataLocal.... in your picture
- Ctrl+Shift+P to open the command palette, search for and select - Python:Select Interpreter
- Select the interpreter with the - msspackage installed
2. Install the mss package for your virtual environment
