Affinity Publisher takes a very long time to start up (I have a decent Win specs - memory, space, etc.). The application seems to get stuck on the loading splash screen while "loading fonts". In my case it took about 6 or 7 minutes to start up. I suspect due to numerous installed fonts on my windows desktop (all purchased with licenses, etc. from trusted sources). After the application starts & is ready for use, unlike Designer, the font selection (lookup) list in this case performed ok. It's mainly the Publisher app startup process that has a performance issue on systems with numerous fonts installed. There's no issue with my other programs like Photoshop, MS Word, etc.
