So Whenever I load up a certain survival world my game exits/crashes less than a minute after joining the world. Note: I only had optifine downloaded (Version: release 1.14.4-Optifine_HD_U_F2) However, the game does the same exact thing in Vanilla (without OptiFine) I have a crash report of the "vanilla" version in the comments if you need it.
