Try 140.4.0 ESR as a work around to give them time to figure out what they broke unless you depend on a feature in 144. [1] Works for me on Linux and Windows. Or try starting 144 in safe mode to disable all addons as a test.

I signed out, flushed all data, disabled all extension but it did not help.
Incognito mode works though..
Hmm.. in normal mode, I see that https://rr5---sn-t0a7ln7d.googlevideo.com is called but gets ns_error_unknown_host but in incognito mode rr5 is not called and all works. Changing to dns over https did not help. But I heard about the AWS outage today and that it has something to do with DNS so i think there's the issue. Though am not sure why incognito works.

The only other thing I could suggest is use the web console network tab to see what requests may be hanging or timing out when not in Incognito mode.
