Squirrellysama

So I downloaded the latest beta version of the New MO2, not having downloaded or tried the previous versions as I'd only just learned of it. And it doesn't start at all. It doesn't give any install options when I open the zip so it just unpacks it in the current folder it's in so it should be portable I guess. But the moment I open the EXE it stops working. First it says it can't locate Skyrim Special Edition in the Steam directory, then after I select it just freezes and gives a blank error message and does nothing. I've attached a screenshot of the error that occurs as soon as I attempt to open the program.

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])"
