The latest version of the mod at the moment "betterarcheology-1.2.0-1.20.1" is been crashing immediately at startup, earlier versions such as "1.1.7" aren't triggering that issue and even with the newest version of the config mod pointed to in "required dependencies" the mod still crashes.

the crash report reads as:
