Won't run Executables After Crash

[Squirrellysama]

I was attempting to port a patch of an armor mod from OLDrim for it's SE version, in the end as part of an effort to get it to work I unloaded the ESP for the OLDrim patch leaving the textures to overwrite the SE version while letting the SE version keep it's esp active (as deactivating or overwriting simply uninstalled the armor mod). When loading the game and attempting to wear the armor the game crashed, not unexpectedly. However now Skyrim won't open, even when I disable and remove both mods. Even worse it seems that it won't open any executable plugins like FNIS or LOOT. LOOT and Wryebash give an error message saying "Failed to spawn 'LOOT.exe' Failed to start process (the parameter is incorrect. [87])"
