modded MC 1.19.2 keeps crashing

[mothb0ne]

so whenever i load up the game it seems as if it's loading fine but when it finishes it says "saving world" and crashes
and when i get said crash it says 

"The game crashed whilst rendering overlay

Error: java.lang.OutOfMemoryError: Java heap space"

does anyone know how to fix this? ive tried allocating memory and it made it worse so ive just left that alone
