Forge version: 1.16.5-36.0.42
Botania version: r411

Steps to reproduce:
Link to crash log: https://gist.github.com/kellixon/2e08cec3eb42f5fa26b2c9db26bfeb10

1. Without botany, everything runs great
2. After adding the mod, the game crashes at startup
3. I have been waiting for a solution to the problem for six months, and I can not play with this mod. What should I do? Where to dig, who to write to?

What I expected to happen:
-normal launch before the game menu
What happened instead:
-crash at the beginning of loading the game

Thanks! Looks like it's a conflict with this mod: https://www.curseforge.com/minecraft/mc-mods/time-speed-mod.
Looks like this was already reported to them. The most we can do is make this injection not required so it doesn't crash.

If we don't know about a problem, how can we fix it?

This looks like a mod compatibility error. Can you add -Dmixin.dumpTargetOnFailure=true to Java arguments, zip up the exported class from .mixin.out/classes and attach it here?

.mixin.out/class
class.zip
ps. all modpack(zip)

Yes, yes, yes. And another my +4 mods (CraftingStation+ExtraTags, Inspirations+Mantle) also started without B3M, which previously crashed with the same error at startup!!!
