After updating to the latest pycharm version (2021.1.3) from 2020.3, it froze when opening a previous project and indexing dependencies. I had to force close it with task manager as it was completely unresponsive. I deleted the recentProjects file so that I could try a different project, and create a new project with a new virtualenv but ran into the same issue. I then uninstalled and reinstalled, but ran into the same issue (perhaps the old installations are still affecting it?)
Issue is on Windows 10. I uploaded the logs I could find. There were some thread dump files which seemed to reference getting locked.
