Impossible to see the end, these video images at the end cover the entire screen.

Under USB Settings I had to change it from 'Transferring files / Android Auto' to 'USB tethering' and the key screen showed up.

Hello merci pour cette vidéo c'est top (désolé je met le commentaire en français, il suffira de faire une traduction). Pour les personnes ayant le soucis que j'ai pu avoir : c'est à dire : même en réalisant ces manipulations la pop'up n'apparaissait pas, il faut avant de rebrancher le téléphone décocher "USB Debugging" une fois branché cocher à nouveau "USB Debugging" pour moi la pop'up n'est apparue que comme cela (après 4 tentatives en laissant "USB debugging" coché aucune pop'up n'apparaissait et le téléphone était toujours "unauthorized") maintenant c'est ok et il apparait sur UE5 comme je le souhaitait. Merci beaucoup.

Merci baucoup d'avoir écrit ce commentaire ❤ Il a marché très très bien pour moi. Je dois vous dire que ce sont des moments comme ce ci que je suis content d'avoir dedié du temps à l'apprentissage du français, même si je fais encore pas mal de fautes.

How do you fix this if you can't boot anymore?

[@imsome1udontneedtoknow856]

did u find out

[@pluto762]

@@imsome1udontneedtoknow856 Yeah, you can't. Or at least I couldn't find a way. You need to be able to boot.
I did manage to fix my issue though by flashing back LOS Recovery, then the OS itself, which gave me back the access to the OS and also to that freaking pop-up.
So, my advice: if you're on LineageOS ROM, and you flashed TWRP recovery, for whatever reason, flash back LineageOS recovery, cause that's gonna solve a lot of the issues.
Also, if you're using a custom ROM and a custom recovery, your External SD card can be a life saver.
