Odd Behavior from the Modlist and weapons (what happened?)

So for some context, a couple of days ago (3?) i was playing the game normally, with a couple of sword mods, gore-mods, and allat stuff. Naturally, It crashes after a little while, due to asset buildup and prolonged time playing. I get off the game for a couple of days. Coming back to it today, i notice something weird, trying to enable some mods from Nexus. My modlist was gone, and I couldn't access my enabled mods at all. This was really making me mad, so I reinstalled the game to try and fix the issue. When i thought it was fixed, i reinstalled some bigger mods (realistic bleeding and ultraviolent sound overhaul). Closing it and reopening it, still; the modmenu blanked. So I just try to play vanilla with those couple of working mods, and notice another off thing. Slashing an npc barely worked, and hooked them on my blade as if i am piercing or stabbing them. Making most weapons like the axe or sword obsolete.
