Looks like the wrong version of Forge or SapManPack. Have you made sure that it's also erroring in CSM/SapManPack and not something else you have installed?

From your short crash log I see it's not finding a method from the ObjectWeb ASM library, indicating your Cauldron version uses an outdated Forge version...
Maybe try this version, as I've used it to test my ManagerPack on while fixing that other cauldron crash, and has a supported Forge version: https://prok.pw/gitlab/Prototik/KCauldron/tree/master

Closing this now. If you still have problems, open up a new issue.
