Can confirm the post above about Scale.PartDB.19x.dll.
I am only able to understand the basics of debugging these logs due to programming in Assembly language, however, i am only capable of programming hardware and not software as i dont know any other language besides Assembly and C++/#. Even still, my knowledge wouldnt get me far enough to understand the code well enough to trace it. I only understand it well enough to get a basic idea of what its doing. That said, Below is the section of Log that lists this error.

I loaded the game with Tweakscale installed just for giggles to see what it would do. Well the game loads, its working fine and i can interact with menus and what not, until i place a part. Once i have placed the part, i can no longer interact with it. Oh yeah, i can also no longer leave the VAB? not sure how that was connected, but, that is my update.
