Forge 1.20.1 incompatibility with Vampirism
JER never displays when Vampirism is installed. Error at line 2437: https://pastebin.com/JNPhgGfL

Doesn't the VanillaRegistries#createLoookup only contain vanilla registry objects and not modded ones?

Usually you get all registry objects (including modded ones) with Level#registryAccess
Also seems very similar to https://github.com/way2muchnoise/JustEnoughResources/issues/412 and https://github.com/way2muchnoise/JustEnoughResources/issues/417 and https://github.com/way2muchnoise/JustEnoughResources/issues/410 For Vampirism, there appears to be a workaround by installing TerraBlender, maybe it works for the other mods as well. However, it would be nice if this could be fixed in JER. Maybe it can be resolved by applying Cheaterpaul's suggestion above.
