When I finally got my phone fixed after a long time, it got formatted, so I had to redownload minecraft and the packs I had. (Side/unrelated note:capes tab is now completely gone. First I get the minecon 2019 cape in 2020 somehow, but now I can't even use any.) Anyways, I wanted to remind myself how minecraft looked with shaders, selecting some ones that were more recent, and working. Then, I went to a familiar shader: the ESTN shaders. When I went to create the world, I noticed that the "discretion for online activity" message appeared, despite me already selecting it to be off and not show again from the first shader. I reselected the box, and selected proceed. The game seemed to slow a little, then freeze between a fadeout between boxes, then crashed. Subsequent attempts yielded similar results, minus the discretion message. The same shader had worked before, before my phone broke, and before the recent updates, but now, it crashes. The fact the shader didn't get updated, but the game did, shows that this is a bug in the game, like with the previously reported breaking of animations. Which, by the way, custom animations with custom or no bones now seem to not allow legs to rotate at all, reintroducing the issue. I've been trying to find any changes on the official wiki relating to shaders in any way to find why it's happening, like I did with the breaking animations, but results have not shown yet. I cannot link the shader file myself, as it exceeds the file size limit by at least 3 megabytes, but I will link to a place it can be downloaded, which is where I got it from. I have also tried multiple other shaders, around 25, and only one other one worked, unless I remember wrong, and it was only the first shader, which I forgot to mention, is the unreal shaders resource pack, which is on the same website as ESTN, where I linked it to. I have also tried different combinations of different experimental features, ones that would have a possible effect, but it didn't change the results.

What was expected:

Shaders selected, and tested to work on previous versions would work in current beta versions.

What happened in reality:

Most, except for two shaders, crashed the game, consistently.

Steps to reproduce:

1. Download, and import ESTN shaders to Minecraft.
2. Open create new world, and apply the ESTN shaders.
3. The result, at least in my case, is a crash, every time.
