Unable to run unit tests in PyCharm

I am trying to run a simple unit test in PyCharm, but getting the following error while running the test case:

```

class com.jetbrains.python.testing.PyTestConfiguration cannot be cast to class com.jetbrains.python.run.PythonRunConfiguration (com.jetbrains.python.testing.PyTestConfiguration and com.jetbrains.python.run.PythonRunConfiguration are in unnamed module of loader com.intellij.ide.plugins.cl.PluginClassLoader @64baed99)

```

My test file is very basic:

from unittest import TestCase

from main import print_hi


class Test(TestCase):
    def test_print_hi(self):
        assert print_hi("name") == "name"

This error is happening for every pycharm project in my M1 MacBook Pro. I can run the test case from my terminal, though. 

My PyCharm version is: PyCharm 2022.2.2 (Professional Edition)

Let me know if any further details will be required from my side.
