So, I've been trying to use the mod in a 1.15.2 Forge Mod Profile, and every time I try to run the game with the 3.0.2-Alpha file, it says the mod failed to load correctly. Attached is the log file generated, can anyone help me with this issue?

Your Forge is too old. Update to a more recent version of forge for 1.15.2
