At the login screen I selected Google account, then picked my Google account. The page loaded some and then prompted for my Google account again, then I picked it again. This isn’t abnormal for me, it always asks twice and then works. After the 2nd time though, I got a “something went wrong” page. The error message is a toString of an object though so it doesn’t say anything.
Anyway, took a screenshot for you to see, plus the dev console that showed the actual error.
After I refreshed the page the editor loaded as usual.
