Hi,
I installed purchased version of Affinity V2 Universal Licence (old version 1.10.5.1345 still installed), but no problems with startups. Only once I startup APhoto and try open RAW, next is freeze and crash, but now is good after restart OS.
Did you try uninstall APhoto, restart OS, and install again?
Maybe it will help.
I think, employees of Serif have a lot of work now with V2 and old software 1.10. Maybe this is a reason, why they have delayed replies.
