Glitchy textures appear when using Deferred Rendering

so, I have been using shaders on Minecraft preview for a while, and recently this bug has been happening that every time I load into a world with shaders, glitchy textures and text appears causing my game to freeze

Steps to Reproduce:

1. add a shader into a Minecraft world on preview with experiments on
2. [load into the world]
3. [fail to load in because it glitches out]

Observed Results:
[glitches out crazy when loading into a world with shaders]

Expected Results:
[it should, like Normal load in and may be a bit laggy, but otherwise it works]

Screenshots/Videos attached: [please attach an image or short video]
