Parts not attaching in editor, node dissapearanece, unable to grab part after

[Sh0ck]

Hey all, I'm using a modded ksp install and I run into this bug in both SPH and VAB when trying to start a new craft or edit an existing one. After picking the main part, some parts are still unavailable to select, and when attached to the existing node on the craft, they don't stay and cause the node to disappear. This makes building anything impossible in the game.

KSP 1.12.5, Breaking Ground, Making Science. 

Video, KSP Log, and mod list are on drive: https://mega.nz/folder/EqAS1DRL#Q8kIyzpkUsYpZcguLJ0hNw

Please help me sort this out; I can't seem to narrow it down to anything, and it works very intermittently. Everything works well without mods. Thanks!
