Bug: "No tests were found"

After upgrading pycharm to the latest version my "django tests" stopped working. 

If I put a correct value in the target field, e.g. "app.tests.SomeTestClass" - then it runs the tests from that class.

When I want to run all tests and leave the target blank - it says "no tests were found".

Now the plot twist: If I set working directory manually to a correct value - pycharm runs all tests correctly (with target value being blank).

I know have absolutely ridiculous situation where two IDENTICAL commands work differently.

1) If "target" is blank the command is:

/home/xxx/anaconda3/envs/xxx/bin/python /home/xxx/pycharm-2021.3.2/plugins/python/helpers/pycharm/django_test_manage.py test /home/xxx/path/to/project

Result: "No tests were found"

2) When I put /home/xxx/path/to/project as working directory, the command is:

/home/xxx/anaconda3/envs/xxx/bin/python /home/xxx/pycharm-2021.3.2/plugins/python/helpers/pycharm/django_test_manage.py test /home/xxx/path/to/project

yup, it's IDENTICAL

And now the tests are running.
