It doesn't work with the law of conservation of energy for one. Except if you assume a framework of universes in which anything goes but then you needn't bother with phisycs at all.

MWI can easily ignore conservation of energy either by only considering in-universe energy or otherwise putting all universes in the same configuration space (much like one of those matter phase graphs showing how possible states grow on one side)

This does still leave plenty of problems around stuff like branching triggers and much more, though
