Laptop won't boot

I can’t boot into my laptop

I can’t event boot Grub, but by booting on the grub of my old manjaro USB I was able to boot in my laptop manjaro with kernel 5.15 (didn’t tried yet 5.19)

Okay I just launch my ssd’s kernel 5.19.4 from my usb stick’s grub and it works well.

The problem is entirely with grub.

Hello,

Are you on the unstable branch ?

Indeed, thou mine stopped to boot just now, 10 hours ago it was just as usual.
Now my laptop tries to boot but end up going straight to the bios.

Well I just did
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyuu
Which reverted from r322 to r261 and it’s working again as usual.

Yeah, Arch are aware of it and hopefully there will be a more general fix soon.
