Affinity Photo version
1.9.2.1035 (Windows, from Affinity Store)
Windows Version
Windows 10 (Pro) version 20H2
Issue
Forgive me if this bug already has been reported.
As a new user coming from GIMP I wanted to bind the "Select Sampled Color" tool to "Shift+O". When using the shortcut, in a document with colored pixels, Affinity Photo just shuts down immediately. I tried changing the shortcut to other combinations as well, eg. "Shift+I", "Ctrl+Q" and "Ctrl+W", with the same result. I didn't try that many shortcut combinations, but I believe the bug affects enough keybinds to be relevant.
If you have any further questions feel free to reply.
