I too, have fully updated ProSeries 2015-2021 years and I installed the latest Windows 11 update called 2023-07 cumulative update preview.  The printing and saving problems are still there.

Oddly, when initially updated ProSeries did correctly print and save a trial return, then it ceased to work after (even after a reboot of the system).

PLEASE get with MicroSoft and have them fix whatever it was that they did in their end of May update.
