opening .py file with QtCreator causes IDE to freeze

Opening a python file causes QtCreator to freeze for me in Ubuntu 20.04. I open conanfile.py files regularly with QtCreator and this didn't happen until the upgrade to 10.0.2.

I tried turning on QtCreator logging, but it hasn't helped as everything freezes and the log ceases to show anything new. I'm not sure how to view logs outside the IDE. Also, if a python file is already open in a session and you try to start that session, the IDE will freeze.
