Hi, I found out your mod has a bug where it temporarily freezes game when the left ctrl key is held in open inventory screen. I got also other mods so it may be the combination, mouse tweaks is one that pops in my mind, but nothing is mapped to left control as far as I can say, although it might be hard-coded.
I just know that removing your mod resolved the issue for me, so it might be a compatibility thing.
