I have the same issue on Ubuntu 22.04.2, `apport-gtk` version is 2.20.11.
There are 4 process of `apport-gtk` running currently and they are running for days already, taking all processing power they can. I have tried to clean up the `/var/crash` directory (simply deleting all files there - crash dump and upload files), but it didn't help, so I have also killed all those four processor-hungry processes. After that, all other apport processes (about 10 to 15 of them) ended themselves and so far nothing has started again.

I'll observe the issue further.
