The errors you posted are mostly secondary errors so they don't give a clear idea of the problem, perhaps the first few errors would be more better. But I think there is enough to make an attempt at correcting the install.
You are missing some changes provided by the mod when the mod is applied through the in-game mod system. There generally are very few causes of this problem.
The simplest being that you forgot to apply the mod during the last install. This can happen because the game will report that a mod is still applied if it was not removed in-game before the next fresh install was started. The active mod list has no idea what mods are actually active, it just tracks in-game mod system changes. Simply make sure the mod is selected in the mod panel and press "Apply".
You may have the mod in Strive's mod folder, but the path may be wrong. This can happen if the mod is inside too many or too few folders or if any of the internal folders was renamed. After applying the mod, there will be a list of files that did not match existing files, if that contains files outside of ".../scripts/aricsexpansion/", then this is the cause.
You may have placed the Strive program folder in a location with restricted privileges for programs to change files. The desktop is generally a great place to avoid this problem. After applying the mod, there will be file read or write errors reported.
