I have similar issue world is crashing with OptiFine but when I remove optifine it works fine.

Crash report: https://www.dropbox.com/s/cqx82duwxxoxwwa/crash-2021-01-16_09.29.37-client.txt?dl=1

having same issue as well

I have this issue too

Can reproduce - same stacktrace with only OptiFine HD U G7 pre1/G6/G5 and create 0.3e installed on forge .37. Make a world, place a cogwheel, save and quit, and then try to open that world again.

made a weird discovery and hopefully someone can reproduce this:

now im using forge- 35.1.37 with preview_OptiFine_1.16.4_HD_U_G6_pre12 and i get the crash

but when i use forge- 35.1.36 with preview_OptiFine_1.16.4_HD_U_G6_pre12 i don't get the crash at all

I have reason to believe that there may be some Forge tomfoolery going on.

I have just tryed switching from forge-35.1.37 to forge-35.1.36 and world is not crashing anymore so yes it is probably forge.
