Your errors exactly match this one https://itch.io/post/2005618. Thus your problem is related to failure to apply the mod through the mod system. As my reply to that briefly post states, this issue can happen from simply forgoing the application of the mod or if the path to the mod is incorrect.
If you applied the mod in-game. then the path is probably wrong. Strive is VERY strict about file paths and any changes to folder names or the number of folder levels will break stuff. Typically people extract the mod into another folder and have the first path but should have the second path.
- /Strive/mods/AricsExpansion v0.9.7/AricsExpansion/info.txt
- /Strive/mods/AricsExpansion/info.txt
Simply fix the path and re-apply the mod.
