Private Island - Character is Default

I seem to be having a few issues when publishing a private island.

When I test my game on PS5 (via UEFN) it runs perfectly, as it should. However when I play the private version (with the private island code provided), my character reverts to the default character and I do not have footstep sounds or vehicle sounds. Everything else works except for that.

Would appreciate any help, thanks.

UPDATE:

After doing a bit of fiddling around, it seems to have something to do with the PS5 Cache. I unplugged the power chord for about a minute or two and everything loaded as it should. Will be keeping my eye on it just in case.

Players are all wearing default outfits, they need to respawn or be eliminated for user selected outfit to apply
