Stuck in emergency mode After formatting a game partition

Hello. So I had a game partition on a second SSD that was in NTFS, that I formatted to ext4 in bazzite. The disk, and especially the partition, was used purely to install games and not for bazzite nor windows. Since then, I'm stuck in emergency mode (with root account locked) when I try to boot to bazzite, both in ostree 0 and 1.
What did I do wrong, and how can I fix this ?
Thanks !
