Unable to add packs to realm

Does this happen for every pack or only certain ones (try one at a time)?
If only certain packs, which ones fail (name and creator)?
Are you able to create a brand new world with those packs and upload that to the realm (in one of the other slots, if not being used)?
What device are you using?

It is only doing it for certain packs. And I noticed that sometimes I world add pack and it would not save than my game freezes and I either have to close my game or it crashes. BTW all the packs I got from  mcpdel.com. Tho packs I am using that don’t work are Mr.Crayfish furniture, more ore tools, more body animations, ultimate morph, worldedit bedrock edition, and mobvote20222. And all the packs are updated. The packs work fine on a world but the second I add them to a realm I have problems. I have tried on the 3 devices I have which are window 11 hp computer, nentendo switch, and iPhone 11 iOS 16.1 my game version is 1.19.51 not even packs from Mc marketplace are working.

Thank you for your report!
