Anyone understands what’s going on here? (Workshop issue)

I saw this before and thought "Oh, guess they deleted those mods?" and unsubscribed from them… and then stuff that was working while this was going on was removed from the game I was playing. Is there any way to fix this to see what the mod is/was? or am I just SOL and have to figure out the hard way by unsubscribing and potentially breaking the game in the process?
