Mysterious Modded Crash

I am using an extensive modded world since I recently got a new computer that can handle it. After some complications, I got it to work. However, after I got an achievement from a mod called "Spelunking" (from Tetra) and when I went to check it in the Advancements menu the game crashed and the game keeps crashes when I try to launch it. The game worked perfectly fine until I went to check advancement, now it refuses to start. I deleted the world & log since it was only 2 minutes old, as well as some suspected mods; but it still crashes. I checked the crash report for errors, not loaded, or disabled but everything looked fine as far as I could tell.
Here is the crash report if you all can gleam anything from it that I overlooked or didn't understand.
EDIT:
I am using 1.15.2 forge

I uninstalled and reinstalled forge, didn't work.

Something I just noticed though is that is when when it crashes there is a message on the right top corner that says "Resource Reload Failed" and it saves world then it goes back to the launcher. I don't know if that means anything or if that is just a thing newer forge crashes work.
Edit V2:
I uninstalled then reinstalled everything and it was TerraForge freaking out with mob & resource generating mods. Removing TerraForge seemed to fix it.

// Uh... Did I do that?
