Texture Packs show Resource Pack Fallback when entering a world

On 1.19.11, Using Resource Packs or Behavior Works Fine.

Updating to 1.19.20 Shows A Pack Fallback Error

Even with vanilla textures.

Steps to Reproduce:

1. Open Minecraft
2. Import a texture pack
3. Create a new world ( or edit an existing world)
4. Add one of the attached resource packs to the world.
5. Enter the world.
6. See the Resource Pack Fallback Error

Observed Results:
Resource Pack Fallback

Low Memory. Textures will have a reduced level of detail.

Expected Results:
This pop-up should not appear.

 

{updated to be a general bug instead of just an rtx resource pack bug, because non-rtx packs and behavior packs aparrently show the bug too}
