Load file from macos to jupyterLab

I was trying to work with JupyterLab on a new macbook with Ventura 13.2.1 installed on it.
Tried to load a file from my computer to the environment. Tried both .xlsx and .csv in every possible path combination. With an without expanduser, abspath, ~, r, etc.
None off them is working. Get the same error message everytime (no such file or directory).
Am I the only one or is this a know issue.
By the way the scripts work perfectly on a windows computer.
