As of 2024-12-09, I am still getting this error but after messing around a bit, I think I may have found a workaround.
Workaround
It seems like you cannot login when you get the error. This time I decided to click on the chat. Nothing loads but now the usual profile icon shows and a banner to login also shows. If the banner doesn't show, the profile options should have the option to sign in.
After signing in, some things may load. For me, it loaded three or four of maybe eighty or hundred of chats I should have. The profile icon doesn't show nor does the status.
As with the prior login issue, reloading the application after signing in with the issues will then finally load properly.
At least, I can use the app in the morning now. I am not sure why waiting several hours will also reach the same state.
