That’s just complaints about source maps, which can be ignored. I’m specifically looking for an error when you select a new theme to activate. Can you go through the activation process for a theme and see if you trigger anything?
From the logs you posted, I see this type of error repeatedly. I’ll paste it here for the convenience of those who come after, in hopes of making it easier to help you!
