pytest 6.0.0 INTERNALERROR with python version 3.8.2

[jitendrs]

pytest==6.0.0
python=3.8.2
OS:- centos/Mac/redhat

I am having error while running pytest cases with @pytest.mark.skip decorator for my test class.
It's seems this issue appears only for pytest version 6.0.0. I am able to run same test case with pytest version 5.4.3

example code:-

@pytest.mark.skip
 def test_get_test_authz_resources(self, apiobj):

     return_value = apiobj.get_client_authz_resources()
     assert return_value != None

Error log:

This is a duplicate of #7559. Should be fixed in 6.0.1 (not released yet).
