Game Crashed on Custom Modpack

[CozyMiel]

I've been working on this custom modpack for a while now, but idk enough about the ins-and-outs of the game unfortunately. I thought at first it was because one particular mod that I love and have been waiting for an update to add to my list, that wasn't it, the game would at least play but crash the game after my frames dropped to single digits. After I had updated all of the mods hoping that this would solve the problem. Instead it made it worse,  when I'd launched the game and its gone through the red loading screen, it crashes.
I get this error code and here is the crash report too: https://mclo.gs/VDq25Zq
"The game crashed whilst rendering overlay Error: java.lang.ExceptionInInitializerError: null Exit Code 1"

Help please~

I Just did and although the game opened it immediately went to an "Error loading mods" page.

It says:
Mod embeddium only supports textrues_embeddium_options 0.0.0-NOT-COMPATIBLE
Currently, textrues_embeddium_options is 0.1.5+mc1.20.1

--edit--

1) Turned off the Embeddium mod and its dependents--The game opened up and is running, but I think that's what was used to run my shaders. So now I have vanilla lighting and textures. The framerate has dropped some too and its taking longer to load the surrounding chunks. No errors, but no shaders.
2) On my other world it froze again when I approached a custom structure from the Hexerei mod. It's telling me that I need to allocate more memory to it, but I don't have any more memory that I can give without locking up my PC altogether. This is a different problem that, unless you have suggestions, I think I'll need to talk with the mod maker about specifically.
