Thanks carl123. Setting renderer to Warp fixed it.

This doesn't happen on my laptop. I've since removed all trace of Affinity on my desktop and reinstalled. Still the same result. Reinstalled an older version - still hangs. I'm thinking it might be the current nvidia driver.

Affinity Photo and Designer both hang when opening a file. I can run the program without issue but as soon as I try to open ANY file, it hangs & becomes unresponsive. I have to force close the app via task manager. I've tried resetting everything by holding CTRL on startup, and also reinstalled Photo. Entry in event viewer just shows the hang: The program Photo.exe version 1.8.5.703 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

I'd like to be able to disable colour channels per layer rather than just globally.
