A couple of days ago, I updated Publisher to 1.10 from 1.8. I'd kept the old version until I was done with a 500-page book on Virginia mammals! (Testing with the 1.10 beta had changed the pagination.)
The new version ran and opened the book fine. Today, when I went to finalize entry forms for our July 4th parade, Publisher crashed at the splash screen. (Later found that Designer and Photo did the same.)
After a lot of wasted reinstalls, etc. I found this thread, and remembered that CCleaner had installed an updated driver for my Radeon R9 360 (16.05.2022 dated 11/5/21). Reverting to the old driver (16.05.2021 dated 26/2/19) failed! Installed Radeon's bloated software, but that did not solve the splash screen crash. Did a System Restore to when I uninstalled Publisher Beta, just before the new driver was installed, and my 1.10 Affinity programs run again!
Hope this helps Affinity debug their problem with Radeon.
