If you have MPM + Excalibur (sometimes other resource packs)

Go into your resource pack (outside of the game) and navigate to the "Lightmap" folder

Inside that folder delete the World0 file. This should resolve the invisible player models

Once you save it you can relog and set the pack back up as your selected pack.

This seems to be an error for MAC users only I have yet to find a fix for this unfortunately :(
