Install finished! I am now reconfiguring my set up.
…However I conveniently forgot to format the EFI partition during set up, and as such, I have two kernel 6.1.3 entries in the boot menu. I have verified that one works well (it is from which I am running my system now). Can anyone help me with cleaning up unwanted systemd-boot entries?
Lesson learned though, do not be hasty and do not do things while running low on sleep.
FINAL EDIT bootctl list and rm’ed everything else I don’t need from the old install. Reinstalling my dear packages now. Thank you so much to everyone who dropped by and helped me out 
Wish you a great morning/day/evening ahead. Will mark this solved for now, with the solution being… reinstall.
