'TypeError: Bases must be types' when trying to import tensorflow

When trying to import tensorflow I get the following error:

  File "E:/Users/jan/Python_Lernen/NN play_data.py", line 2, in <module>
    import tensorflow as tf

TypeError: bases must be types

The IDE I'm using is PyCharm Community Edition 2021.1.1 x64. The python version is 3.7.10, tensorflow version is 2.0, cuDNN version is 7.4.2.24, CUDA version is 10.0.

I'm running the same setup at home, without any issues. I've tried reinstalling everything, didn't help.

Does anybody have any ideas?
