At the end of October had a low power outage that any thing that need more than 250 watts did not work for 2 days. Lucky my computer still worked after that an Update for Catalina Security. I updated then open Poser 11 Pro selected Victoria 4 and Poser crashed. I again open Poser selected Victoria 4 Poser crashed again. I selected different figures Micheal 4, Dawn, Dusk, La Femme, La Homme Poser crashes each time. So I uninstalled Poser and reinstalled it now every time it starts up to the Poser app to internet connection apply and deny and goes to the scene screen and loads up it crashes/quits.

Rebooted my computer still crashes

removed item in App support still crashes

uninstall and reinstall still crashes

put in old Poser 11 by SmithMicro no crash but it no long supported.

It kind of sounds like that power problem may have damaged the computer. Voltage fluctuations are always bad. I've had systems fried even though they were connected to serge protectors. Also Catalina? Try updating to Big Sir. that's the current version of MacOS.

Personally, I'm sticking with High Sierra -- not that that's eliminated P11 crashes. As for power outages, consider getting an uninterruptable power supply (UPS). Has saved my bacon a few times. A lot cheaper than buying a new Mac.

I just found this and if you have Intel HD 4000 graphics in your Mac, this is likely the cause: https://discussions.apple.com/thread/253309962

The security update at the end of October broke the Intel graphics driver. Still waiting on Apple to fix this.
