This solutionworks about editing out from json file:
"
So there are two things you need to erase to fully get rid of the mod. If you go to the subscribed mod folder you can delete the mod’s folder there but as soon as you reenter the game it will just show up again because it doesn’t remove the subscription.
The second thing you can do to fully delete the mod from your subscribed list is to remove it from the mods-status.json file.
Find the mod name and delete from { to } around the mod. Be careful though because if you delete part of another mod it will break that one.
Once it is removed from both places it can be reinstalled and that seems to work. (I have dealt with this issue a lot)
