BAS developers will custom extend the fingerprints to fit in there when BAS is released. This means that his current BASver browser and currently downloaded ver25.3.8 are not suitable. You have to go back in time. It is necessary to match the fingerprint downloaded in the past = BAS ver at that time. It drops more than half in regeneration. This is because his current fingerprint and his BAS browser fingerprint don't match. Playback fails. I've been testing this all along to figure out why it crashes on playback. The fingerprint should match the time and Bas release time. There is a BASver that is okay even if there is some deviation. It was a custom change that didn't affect playback. There will be major BAS updates over time. At that time, even if you download the fingerprint now, please do not forget that the fingerprint will be changed according to the current latest BAS. Simple.
by the way,
Don't use Firefox or Safari with YouTube. Since time immemorial, his this his two kinds of browsers do not work.
YaBrowser and Chrome worked until last year.
