if you need to delete any mods i will recommend downloading the mod again (if you don't have it), look inside the mod folder that you just download for the names and locations of the files, then delete the files with the same name and location from your GTA V folder (some files are shared like AdvancedHookV.dll, Albo1125.Common.dll RAGENativeUI.XML and some others), if you want to disable ASI manager, as soon as you RAGEPluginHook is loading, hit the button settings ( low left corner next to the RED X) go to plugins and disable it from there, hope this help in any way.
