Pycharm freezing after running code

I'm running a python script in Pycharm for my experiments. I'm gathering data using some peripherals and this usually takes 3-8 hours. My code is working fine but after changing some parameters, I'm getting an unknown error when running the code again and Pycharm actually freezes. I have to end Pycharm in task manager before I can run the script again.

What I'm experiencing is similar to this question but I'm already using version 2021.1.2.
