Pycharm error: "Process finished with exit code -1073741819 (0xC0000005)"

Since moving from Spyder to PyCharm, when importing matplotlib, I regularly get the error:

Backend Qt5Agg is interactive backend. Turning interactive mode on.

Process finished with exit code -1073741819 (0xC0000005)

This error comes up before I can set the backend to something else. Restarting python or the PC does nothing, but switching to a new conda environment fixes the issue. I then get

Backend Qt5Agg is interactive backend. Turning interactive mode on.

And everything is fine.

I'm assuming this is related to pyCharm, but if anyone has any ideas, they would be much appreciated! Making fresh environments every time I get this issue is annoying!
