Frozen 2 Resource or behaviour pack has failed to load leaving the adventure map useless.

Frozen 2 Resource or behaviour pack has failed to load leaving the adventure map useless. I bought it the other day one my account and it worked fine then i tried to play it the next day and it wouldn’t work. I then purchased it on another account to see if it would work and it didn’t. I figured it was a bug however there was a bug fix update released today and nothing has changed. Please help

Thanks In Advance
