Shaders do not work in Bedrock Edition (Win 10)

Descriptions:

I entered a world where shaders ESBE and Tint have successfully operated. But in the version 1.16.201 Hotfix, I find that either the shader can't operate in the world (the world looks the same way without shader) (example: shader ESBE), or the shader has some glitch with the sky of the world turn to completely white (example: shader Tint). Note that there's no wrong with the shaders, for I have used them before, but recently something is wrong.

Hope the screenshots may help.

Expectation(s):

These shaders can correctly operate with no glitch.

Ways to reproduce:

1. Create any world in Bedrock Edition (Windows 10) under version 1.16.201.

2. Attach any shader to it.

3. Open the world with and without the shader to see what happen.
