Microsoft teams add-on in google calendar doesn't work

Question

In the past, I was able to add a microsoft teams meeting in my google calendar. But now, it stopped working. When I try to add a microsoft teams meeting, I get an error "cannot create meeting"

I tried to delete the add-on and reinstalling it, nothing helps. When I try to sign in, it gives a "something went wrong" error, after the popup says "you are logged in, close this window to proceed"

What am I doing wrong? Pleas help me out, because this is annoying.
