Grub 2:2.06.r322.gd9b4638c5-1 won't boot and goes straight to the BIOS after update

hey so i tried the instructions on this thread by @sradjoker. the grub-install command showed no errors, i rebooted and was welcomed by the pink endeavour grub screen but then i got this:

IMG_20220826_110327

and after pressing some key and exiting i arrived at this screen:

IMG_20220826_110337

i picked the second option and was able to boot normally.
