Heya, for a while now I had the following errors show up when booting:
error: file ’/boot/grub/…/bli.mod’ not found
error: out of memory.
I can just press any key to continue and it would boot normally.
Does someone know what the issue might be?
I already tried to find a fix or any other topic with a similar issue, to no avail (at least with the “bli.mod” one).
Big thanks in advance!
Welcome to the forum! 
Are you using grub-customizer?
I am not using it.
Can you show the output of terminal commands
lsblk -fm
df -hT
And you could reinstall the grub package:
sudo pacman -Syu grub
Here is the output of the commands:

I also tried reinstalling the grub package, but the issue remained.
Unfortunately the output looks unfamiliar to me, since you are using snaps.
So I hope someone who knows about snaps could help here.
