Edit: managed to boot by reinstalling grub, reinstalling the kernel (latest) with Artix’ own basestrap script and then updating grub from a live USB. System saved. Now it won’t accept a new IP from my dhcp server but that’s tomorrow’s problem. Thank you all for your quick respones! 🥰

Error log:

Should I adjust something in fstab from a live USB or can I point to the root partition from GRUB’s CLI?
