Cardinal-Components-API v2.4.2 will crash if the game is started with Optifabric also enabled. Disabling either 1 or the other will enable the game to boot correctly, but not together. Issue repeatable with versions 2.4.0, 2.4.1 & 2.4.2

That from the Logs Folder? I can certainly drop you that. There are some other issues in there, I'm aware. Which I've fixed in another instance, but this one I can't seem to correct.
I should note I actually got it working with the version meant for 1.16.2? maybe 3 on a 1.16.1 instance, but upon activating Shaders of any kind I get the loading screen over the top of the gameplay and can still hear the sounds ingame.

Huh, 2.4.2 did not fix it ? Could you post a crash report ?

Well the error in your log is coming from Patchouli, not Cardinal Components. I don't think I can help much with that.
