Preferences/settings including back up location, license activation, suddenly disappeared, known issue?

I opened up my laptop to use scrivener (which was already open) and discovered that Scrivener was no longer activated, not using system default dark mode like it was set to, had reverted to default fonts, did not have a back up location set.

Reopening scrivener didn’t change anything and neither did rebooting the laptop. To be clear this happened after I woke up my laptop when scrivener was already opened.

Is this a known issue with scrivener or was it possibly my laptop or the OS instead?

(This is on Catalina with scrivener 3.)
