At 04-Aug-2022 06:52:19 I ended up in an infinite loop at Twitter: I could not log-out, but I could also not continue. The remedy was nevertheless easy, I simply had to correct the URL to twitter.com again.
It is noteworthy that even a large internet company like Twitter produces these kinds of errors.
Added 29-Jan-2023: Today I observed a similar/same error. Screenshot is below.
