until you can run the IDE under a debugger and report where it is hanging, you probably won't get much help on this kind of a problem. There are 1000 reasons why this could happen so any forum input would be a WAG at best.
Run the IDE under a debugger and break it when you see utilization peg during exit...then do a stack backtrace to get an idea where it is hanging. This of course assumes that it is not actually terminating, and you need to force kill it as @ChrisA mentioned.
If it is pegging momentarily and then exiting normally then "don't worry bout it!"

The mac activity monitor is pretty good in the absence of a debugger. Find the process, double click, and then click "sample". This generates a stack trace plus some other stuff.
There's also useful information in the process window, such as open files, etc.

Any resolution? I'm having this on macOS with Qt Creator 19.0.2. After quitting, Activity Monitor shows CPU at 100% until I force-quit.

Same issue here on macOS with Qt Creator 19.0.2 — following this thread in case anyone finds a fix.
