I didn’t manage to find a way to reproduce it in most of the devices but I know that it is related to dispose() on textures (cubetextures) and the error is:
Unfortunatly I cannot reproduce that on my own devices so I need the help from a friend to test this (Pocophone mobile).
Thank you!
Hi you don’t provide enough informations to debug, we need a playground 
… but I already saw this error when I set an object witch is not a texture to a texture. Maybe you disposed a texture and tried to set the disposed object to a texture chanel ?
You are right some devices do not wait until the texture is properly loaded using promises did the work, thank you!
