There are a few compatibility issues with Curios API as far as I know. Here is the https://pastebin.com/mSiUPF68 Crash Log which refers to what happened. If it isn't a compatibility issue, I hope someone would let me know what type of issue it is, or where I should be posting this issue.

Caused by https://www.curseforge.com/minecraft/mc-mods/keepcuriosinventory

(aka this is unrelated to apotheosis)

Has been incompatible for close to a year now: TheIllusiveC4/Curios@d5095df#diff-ba869a5fa4efad659f105f233162b60160424e2827e8efceef0a50c6b4308d86

Ohh thank you for letting me know 🙏 The crashing unfortunately hasn't stopped even after I uninstalled the mod, but then it wasn't Apotheosis' issue. Thank you again for the help =D
