Manjaro constantly winds up having really weird issues, they hold packages back in order to make it more stable, but it honestly just broke things far more often then upstream arch did for me. Manjaro and it’s community is also riddled with really weird issues. It was pointed out to me a while ago that manjaro did some updates that broke grub customizer, and when people were trying to figure out what broke and how to fix it, Manjaro instead not only removed grub customizer, but made it conflict with the grub they had so people working on trying to fix it got a shovel full of go fuckyourself in the face
