Hello!
We have 2 users with 2 different computers reporting the same issue with their prime files.
I don’t know if it has something to do with the latest august Windows 11 Cumulative update (KB5121003)?
The issue started happening yesterday after the users updated their Windows 11.

When we try to Save as PDF or use the Print function we get the same errors. And we have tried several PDF printers. It only creates a .PDF file with 0kb in size.

I uploaded 2 files that we are experiencing this issue with.

Seems OK for me here in USA. My latest Windows 11 Pro updates are:

Same issue here at all licensed stations (Mcad version 11, 11-01 and 12.0) with Windows 11 Pro (USA); printing to local printers not working at all and printing nor save as PDF (results in an error message). Security updates were installed on 8/12. Any other suggestions?
