I had a similar problem wit my PC,
Quoting my note at top:
"My PC AMD Ryzen 7 1700 8-Core processor, 16MB RAM, NVIDIA GeForce GTX 1060 3GB, Windows 11 and Affinity Photo v. 2.2.1 installed on a Samsung SSD 980 PRO 1TB (SSD) and the same problem you have, since I installed v. 2.2.1! I've already reinstalled older versions ( 2.0.0, 2.0.4, 1.9.1, 1.10.0, 1.10.5, ...!!). Same problem ( which didn't happened before )."
I did then upgrade my NVIDIA Driver ( 517.40-desktop-win10-win11-64bit-international-nsd-dch-whql ) to latest the version recommended by them ( 546.01-desktop-win10-win11-64bit-international-dch-whql ), and did a complete re-installation of Affinity 2.2.1. It now works perfectly!! In my case at least, it wasn't an Affinity problem!!
