I might be missing something, but I'll give an update if I recall any extra details. dll files of MO2 indicating they're blocked, but I don't see anything indicating they aren't either.
I don't see anything in the properties of the.
SSE version 1.5.80, SKSE version 2.0.16, MO2 version, CK version 1.5.73 (but I've also used 1.5.3).CK runs just fine through the bethnet launcher and directly from the folder The only thing I could think of that hasn't been affected by my troubleshooting was that there was a Windows 10 update between when CK last worked and now.Mod Organizer is not installed onto the steam or skyrim folders.In-game SKSE w/o mods seems to run just fine. SkyrimSELauncher.exe appears to be working at first but simply closes out with no follow-up or error when I hit play.Creation kit was not installed as a mod (not that I'd know how to install CK in particular as a mod) so it's not available in the left pane.I have steam installed in the D: drive in a self-made folder, but it is still titled D:\Program Files (x86). I am aware that installing in program files causes issues.Temporarily disabling firewall and AV entirely.Making firewall and AV exceptions for MO2 and CK.I'm willing to wipe the folder in its entirety if anyone thinks that might warrant a different result. ( SKSE is the only thing installed, and it's installed manually.).
Renaming MO2's SSE mod folder so the list would be not only entirely disabled but entirely empty.Reinstalling CK at least thrice, and even the bethnet launcher once (I made sure CK was installed in the SSE directory).I've verified the integrity of the game files twice between these two times. Reinstalling Skyrim SE twice, making sure the whole folder was wiped before reinstalling the second time.During troubleshooting, I realized MO2 has the same issue with SSE and the SSE launcher. Whenever I try to run CK through MO2, it simply locks up for a bit before unlocking without any sort of error. Creation kit used to work fine, but at some point at the end of this week while I was installing mods for SSE, it decided it no longer wanted to cooperate. I've been troubleshooting this for two days now and I still cannot find the cause.
