It seems you posted the message here and the errors under Aric's mod, which is a separate mod though this one is derived from that one. Not exactly sure what's going on and which mods you actually have, but based on those errors you at least have Ralph's mod.
Either way neither of these two mods is compatible with the more body parts mod as it is based on version 1.0d Strive, whereas these mods were based on 0.5.25 with my patches. Even then they change the game in ways that are contradictory.
Neither of these two mods have a standard installations which causes most of the problems especially when accompanied by normal mods. For Ralph's mod, people often apply the aricsexpansion mod when they apply the normal mods, which breaks everything because Ralph's program folder contains changes that were not included in the aricsexpansion mod folder.
Based on the errors I found that your person.gd file is at least 3 lines shorter than expected. Also you are missing hybriddict from description.gd which should not happen unless you were moving files into the program folder as the mod system should not remove it. You may have corrupted the program folder and may need to extract a new copy from Ralph's mod archive.
Edit: your errors appear to be nearly identical to https://itch.io/post/2226559
