ucrtbase.dll Makes My Game Crash

[Rusty Shackleford]

No matter what, the game crashes when I do anything that involves a load screen on any of my saves. Actually loading the game works but when I try to open a door, that's when the CTD happens. Trainwreck tells me it's due to ucrtbase.dll. I have the most up to date version in my System32 folder and have repaired/reinstalled Visual C++ twice and THIS game still crashes. It worked fine two days ago. Anyone else have this same issue?

Any mods installed?
Have you ever had mods installed that you may have removed?

The only mods I had installed since yesterday when this started happening are Alternate Vasco, CharGenMenu, StarLuminous, Rotated Engines and Rotated Bays and I had only updated them. I suppose I could disable those or some other .dll mods that might be conflicting with ucrtbase.dll somehow but I'm not sure how that would be possible...

Edit: Just figured it out. StarLuminous messes with lighting a lot. Disabling that let me finally leave the Lodge!

StarLuminous also just updated. But yeah sounds like you had a conflict there. I'd install LOOT and let it check your load order for starters.

Glad you made progress. Enjoy.

Also make sure you have no mods installed that contain an .esp

Try repairing or reinstalling Visual C++.... See what happens.

I explained I did that already and it didn't help. I already found the issue though.

Yeah, I just figured out what was wrong. I also have Royal Weathers. Having StarLuminous below that in my load order leads to a crash. Having it above it doesn't.
