Are you setting the randomTickSpeed game rule to false? You're supposed to set it to a number.

Also please put your crash report as a PASTE next time, as described in the crash report section. I'll fix it for you this time, do not do that again.

I also noticed you lied; you ticked the box stating you were in a supported environment (meaning without OptiFine) but you are using OptiFine. Please test again without OptiFine.

Any updates?
