I actually did have admin privileges on loot, but unfortunately revoking admin didn't solve it. Also i gave admin after plugins disappeared hoping that it would fix it, but that's good to know for future reference so i know what not to do in my scenario.
when i launch the game every mod (from what i can tell) is working still; weapons, armor, character, environment, gameplay. Just with severe performance loss and extremely long load screens. probably bc i deleted the loot files from "C:\Users\MyPC\AppData\Local\LOOT" that i originally setup before this occurred.
It was really bizarre because everything was working and the game ran meticulously (before deleting local loot files) the night before; fast load times, no ctds and steady 40fps over Boston. (turned collision of, went through truestorms settings, spamming things with lots of visual/lighting fx. trying to crash the game). Then the next day i was playing and wanted to edit something and discovered the tools stopped working for no apparent reason.
so i installed the archived versions of LOOT and MO onto the D drive, ensuring to unblock each. created a portable instance, set base directory inside of "D/Mod Organizer 2", installed dummy.esp and loot still won't show it. Didn't run as admin. getting the same "[warning]: Blocking load of resource" from loot, and empty usvfs logs still.
