Broken weapon texture in the hands of slain NPCs. (Fallout 4)

On the game of the latest version with mods (the list is large, very), the texture of the weapon in the hands of the killed NPCs breaks. If they drop the gun, then it's okay. Here is an example of the problem on the screenshot. How can this be fixed? (No need to write "delete mods", I know the point in them, but I caught a glimpse of a topic with a similar problem, and as far as I remember, a mod was proposed there, thanks to which NPCs dropped their weapons after death, and did not hold them in their hands. there are still options, suggest, thank you in advance for your help. And also problems with getting weapons, sometimes it sticks for 2-3 seconds and is empty in the hands, nothing shoots. Only 3 new guns from mods, and even standard game weapons stick.
PS I've been a beginner and if you had, do not throw stones, do not fully accustomed to the forum and to dig into the pile so reluctantly.
