When playing with addons it is stated that there will be unexpected encounters with errors. But this error is when you use a mass amount of the marketplace Add-ons, maybe unofficial Add-ons as well. I have 23 Add-ons enabled, pretty much all of the Add-ons excluding alternate versions. The game textures from a texture pack and/or the default textures appear as bright magenta. This could range from lanterns, torch smoke, blocks, to even the skybox. While I understand the Add-ons are experimental it makes no sense how official marketplace Add-ons could possibly effect how textures load.
This is repeatable as I have done multiple new worlds with them enabled and all of them has had the same result.
Most recent bedrock version(1.20.72), all experiments enabled,23 Add-ons active
