Cannot debug in remote SSH mode Follow

Hi. I am keep getting the following error in a debug mode:

in a virtual env: ...anaconda3/envs/<nama_of_my_virt_env>/lib/python3.10/site-packages/werkzeug/security.py

...line 15, in <module>
    sep for sep in [os.path.sep, os.path.altsep] if sep is not None and sep != "/"
AttributeError: module 'posixpath' has no attribute 'sep'

python-BaseException

This error comes up only in debugging mode.

Do you have any idea, what it could be?

Thanks
