Hi, The newest versions (0.0.5 & 0.0.6) seem to be causing an error loading the Universal Mod Core on 1.16.5.
When I load with the previous version (0.0.4-HOTFIX-1) it works fine. every attempt I have the latest UMC installed (1.1.3).

I am using Forge version 1.16.5-forge-36.2.34, UniversalModCore-1.16.5-forge-1.1.3, and LandOfSignals-1.16.5-forge-0.0.4-HOTFIX-1 (Works) / LandOfSignals-1.16.5-forge-0.0.5 (Crashes) / LandOfSignals-1.16.5-forge-0.0.6 (Crashes)

All other mods are unchanged and work fine with version 0.0.4

Error Screen thrown:
Forge Crash log: crash-2022-07-04_00.20.54-fml.txt
Minecraft Log: latest.log

I have just tried to load the mods in isolation (without the rest of my other mods) however the same result occurred. So I don't believe it is a clash with any other mods.
I also tried to load them in isolation on the latest forge build (1.16.5-forge-36.2.35), and an older known stable build (1.16.5-forge-36.2.20) but again failed to load on both.

Seems to be an issue with the current UMC version, I will redirect the issue and notify of any changes regarding this bug.

Fixed with 0.0.7 (released today)
Fixed with 1.0.0 (upcoming release)
