´ERROR: file or directory not found: for´ - Exit Code 4 - Windows

I'm running pytest with pytest-azurepipelines in a CI-Pipeline on Azure. For Linux everything works fine but for Windows i get an error when calling

python -m pytest -vvv --debug --test-run-title='Test for OS $(imageName) with Python $(python.version)'

Here is the output of the pipeline

I have the same setup (of course with different tests) in a different Pipeline where i use pytest 6.2.4. There everything works as expected (for Linux and Windows)

Does anybody has an idea what the problem could be?
