This article explains how to uninstall a mod
Remove the mod from ModLoadOrder.txt
This step should be done whenever a mod is uninstalled. Just remove the line with the mod’s name.
Delete the mod
Open the /mods/ folder inside your game’s directory and delete the folder of the mod you want to uninstall.
Applying the new load order (IMPORTANT)
After uninstalling a mod, some other mods can have files that were overridden by files in the uninstalled mod. These files will not be loaded until the new load order is applied. To do this, simply run RyuModManagerCLI.exe again and wait for the changes to be applied.
