Since something similar happened to me a moment ago and I confirmed the case in their discord;
Are you running basegame v.525 or have you any of the .525 bugfixes applies - it was confirmed that Aric's mod runs on base .525. and is incompatible with any of the bugfixes on its own.
Also; for updating mods you have to either reset the game to its original files first (reset function via mod menu - but be aware that that doesn't work with files formerly replaced by hand - or just a simple fresh installation/extraction of the game folder) - and it can't hurt to delete 'FileOrder.ini' in the mods folder as well as 'progressdata' & 'settings.ini' in ..user/appdata/roaming/strive.
Not sure what exactly is necessary, but as long as you start a new game, getting fresh versions of those files can't really hurt.
