Oh, Noticed that this still happened after downgrading to lover version of the mod. Very sorry!

Basically I just saw that this was the last mod it loaded before crash, you know, in the bottom left corner. Again, very sorry!

Found the trouble maker. CurseForge Desktop instead of updating, decided to remove one of the mods I have. The game still thought the mod was there. Had to manually update the mod.
