Hello Aideen.
The issue appears to be related to the mods you are running. This might be either an issue with the mod itself which has to be fixed by the mod creator, or the mod is corrupted.
We suggest that you try to uninstall/unsubscribe all your mods, then verify the game data and re-download the mods again. If the issue still persists upon doing so, then it is very likely an issue within the mod itself.
