I keep getting an error with the CurseForge Zombie Apocalypse mod

[CountDracus]

My game keeps crashing and the error that pops up is "The game crashed whilst rendering ingredient Error: java.lang.IllegalStateException: Not building! Exit Code: -1". I've never had to fix these kind of errors and not sure where to begin. I removed the section about my system information at the bottom. Please help.

The crash report is as follows:
