Not exactly certain of how you managed it, but you have an error on line 2594 of a file that should only have 1846 lines. The only way I can think of for getting that result would be using the patch files portion("Put in Strive Game Files") of aric's mod as the mod folder. The entire "AricsExpansion" folder is generally put into the "/Strive/mods/" folder, though the portion you have there can be left out.
Depending on how it was done you may have corrupted the pre-merged Strive program folder and may need to start with a fresh extraction. Otherwise you may be able to un-apply all mods, correct the mod folder, and re-apply mods.
