I am having this issue as well. I cannot replace the map and I cannot change the resource packs for that map.
I can also confirm that this is also an issue on Windows 10 Bedrock v1.16.0.
(Using the PureBDCraft Skin in the screenshot.)
[media]I have this same issue with Bedrock 1.12.0 as well. I have a custom skin and I don't know if I have to do something to update the skin or if it is a different problem. I usually get Alex's skin–perhaps I'm using her arms?
Here's the skin I have been using for a loooong time in the game for both Java and Bedrock:

I have noticed in 1.19.50 that any texture pack is not working right now. I have tried Grunge BDcraft, Pure BDcraft and the Fantasy Texture Pack. This is affecting when you set the pack and checking the box to require your players to use the selected pack as well as clearing any custom pack and letting your players use whatever pack they want.
I have also seen a box added to the resource pack list next to each of the custom pack files labeled "Unknown Name" and the file for Pure BDcraft also had the addition for the notation of "Errors: 1"
