The screenshot you provided shows pretty much what it looks like when the invisible command is used.

If its not that (or a mod calling on that function and forgetting to release it). Then there is a model your character is using that isn’t present or lost its reference. You’ll need to either use a mod feature to change your character’s body (like a shapeshift or what not) if one is present, or you’ll need to recreate your character.

Here’s a good question, when loading into Singleplayer, with the same modlist, does the problem exist there too?
