Resource Packs Not Loading Properly On Realms+

Resource packs worked before 1.16 on realms, now they dont load any texture and have Fortnite-like sounds when opening chest, getting hit.

 

For example: downloaded Dokucraft from their website, it has always worked since its creation, tried uploading the resource pack from pc to realm, and went into game no resources load in, but get some weird sounds when opening chest and many more weird sounds.
