Installing Arch is a lot easier than fixing a bad Manjaro update. I get that it’s intimidating, but it’s really quite easy if you can follow instructions, but budget a couple hours your first time because you’ll probably second-guess everything. The second time should be more like 30 min.
'Till you figure out that, on Arch, if you missed/broke anything, you can boot into the Arch USB, mount your root into /mnt, and arch-chroot in to fix whatever is broken
