Have new imac that was running Big Sur out of the box. Downloaded PyCharm CE and used for about 24 hours. Did Mosh's Python beginner class. All seemed good and I LOVED PyCharm. Next day I restarted Mac to allow it to update Big Sur to 11.4. Now PyCharm CE will not start. I re-installed and same thing. It bounces a few times and then nothing.
I went into console and found this error:
Jul 20 21:21:50 Peters-iMac com.apple.xpc.launchd: Coalition Cache Hit: app<application.com.jetbrains.pycharm.1047936.1048772(501)> 
Thanks in advance for help!
