It's probably referring to Blocks.CHEST, but no idea why that is throwing a NoSuchFieldError. You'll need to find the mod responsible.

Ugh... you are using the DEV jar.... I knew posting it on curse was a bad idea.

Aha , I.m wrong
I download this .jar from mirror2 "Download via CurseForge",then lists has a DEV.

They are both on the same page, the Development (not obfuscated) at the bottom, the Production (obfuscated) version at the top. I probably won't be posting the dev versions on there again since it appears to be confusing people.

+1 on this. Here's my log from client crash.

The game loads fine for me with 10.1.0, so I think this may be a mod compatibility issue of some sort.
