This error has been reproduced since they added volumetric fog to the delayed version of Android, it is generally very common on devices with Mali GPU.
How does this bug work? Well, for them you have to use any kind of resource pack that allows you to enable delayed preview, then create a world and activate delayed preview Along with the volumetric fog options, finally when you go to play you will see that the screen is almost completely black with parts of red, green and blue colors with certain points of bright colors, as I said before this error works with any kind of deferred package and there is no way to fix it manually, the only option is to completely disable fog volumetric.
Steps:
1.Open your Minecraft bedrock
2.Create a world that allows you to enable deferred and activate a resource pack with pbr capabilities
3.Start playing and activate delayed preview
4.Activate volumetric fog with any type of quality, low, medium, high or ultra
5.When you exit the settings screen you will see that your screen is completely dark, preventing you from playing Minecraft Bedrock.
6.I tried changing the quality of the volumetric fog in settings and you will see how the error gets worse

• PS: I have already reproduced the error in different versions with different resource packs with PBR but the problem persists
