Great to hear you may have solved this. Not to burst the bubble, but I dont think the issue was down to textures (atleast not alone). I am no expert, but I dont see how a texture file can interact in such a way to cause a Papyrus error.

From my own experience, and from many others, I don't think SkyUI is that buggy. If you untick all your mods and just load the game with SkyUI only on a fresh game, does that work? Steam doesnt overwrite SKSE in anyway, especialy since using MO doesnt place the files in the steam folder like a manual install. I am using a modified STEP setup, along with a number of non STEP mods, current non beta SKSE, and have had no problems with SkyUI. I am curious now though, could you use the spoiler tag and paste your ini contents from the 'Documents/My Games/Skyrim' as well as from inside MO?

If you use MO, have you checked the ini settings in MO, since those are used when launchign through MO.

This is why I love MO compared to previous STEP guides. Try scaling back and deselecting some. Sounds like a script heavy run, which is a common issue. Looking at your sig for the computer setup, large texture mods would be a guess, something I have hit before with a STEP guide on my own 1GB GTX285

I would try to delete SKYUI in MO from within MO, then check the MO folder for any remaining named files. After that download a fresh up to date version from nexus, perhaps on a different server (some servers have caused me problems before), and install that to try.

Other than double checking those errors and the SKYUI page on Nexus, I am stumped, especialy when everything else works for you. Perhaps a mod conflict is stopping it work. Cuold try the console script repair command mentioned in the readme

Just want to cover the obvious here, but did you add the SKSE as an executable into MO, then run it from MO?

Sounds like its the long road of trying to disable mods and see if it helps. Could try without the lighting mods and the ENB, though if disabling the ENB didnt help perhaps just disabling the lighting mods. What if you remove the ENB rather than disable? I havent tried an ENB so far, so I am unfamiliar with the process atm.

Sounds simialr to a problem I have had previously, and for me it was down to being overly enthusiastic with mods from STEP. I had random crashes, rare driver failure, and got to the point where whole computer would lock up on crashing. The ENB boost and removal/downgrade of some mods helped get past this for me. Now I run 317 mods, involving 175 activated ESP's, and no crashes. Not too bad for an average system. Running a selective extended STEP btw at the moment through MO.

For load order, use latest MO and run LOOT, should sort out any obvious load order problems atleast. Stuttering as you turn, I have something similar. Sounds like its down to lighting, so perhaps a mod related to lighting. I dont use an ENB myself as I dont think my machine can handle it with everything else I have.

Try disabling the 3 RCRN plugins and see what happens. I used to use that with my modified STEP setup, but it did have a performance hit. Think its the volumetric vog thats the main pain. Could also try reseting your ini options and alter as per STEP only incase you altered something too much. Btw, when did the performance drop start? It sounds like you were running fine. Perhaps review what you did before the performance drop would help.

Sounds like a similar issue to this fellow: https://forum.step-project.com/topic/4842-skyui-mo/?do=findComment&comment=78356 What version of NMM are you using through MO? ill grab a copy of the mod and try to install in a mo EDIT: Justr tried the mod, got the same error. I was running 0.48.2, changed to latest, and still got same error on this mod.

What version of NMM do you have MO using? EDIT: ill grab a copy of the mod and try to install in a mo EDIT2: I already have it through MO, and not had a problem isntalling. SKSE though I did not install thrugh MO as its a staple thing for Skyrim. EDIT3: Same issue as this fellow: https://forum.step-project.com/topic/4844-issues-installing-deadly-dragons-in-mod-organizer/?do=findComment&comment=78358
