I don’t have error logs for these as my internet was out at the time, but after playing a few hours I encountered a couple things (sorry if these are already documented!)
Rarely, I will crash when collecting an enchanted gem; it happened twice while enchanting 25 gems. Once it even ate the gems out of the ritual and forced me to make two more! I don’t know if this is related to Paragon cores, though I got about five safely as well.
An extremely weird bug; I once mis-pressed the menu button the same moment I ascended stairs, making the game hang and spit out an error log when I closed it. Not really something that would happen often, but worth mentioning.
