Now the program crashes every time I try to print anything. PDF too.

Close Proseries and go to your Windows Programs/Apps menu and scroll down to Proseries 2024 and run the REPAIR UPDATES option. 

Maybe the update yesterday/this morning didnt install properly...or maybe it had a terrible glitch that rode along with it, repair updates and see if that helps or not.  If it is a glitch, we'll see many more complaints in here this morning.

Tried twice - no difference. But thanks for the suggestion. Anyone else having this problem?

Did you ever use bullzip, a pdf printer.. I know you said you tried to print to pdf and it still crashed but this is a different step.  Bullzip, which is free will be a an actual printer that you can select. https://www.bullzip.com/

I know this is not the optium outcome but maybe see if you can print to bullzip.
