Hello @arnespremberg 
Welcome to Kinsta Community!
Iām sorry to hear that youāre having this issue.
The log entries you shared donāt show any particular issue. Can you please provide the entire main.log?
I also see that my colleague replied to you here: DevKinsta does not open, stuck on "Updating site WordPress configurations..." - #2 by Adrian_L
