I had my mountain bike stored away for a while and wanted to ride again so i cleaned it up and was checking the shifting and noticed that the rear derailleur, when shifting up, will move forward like normal, but then when shifting down will stay in that place and cause the chain to become loose.

Turn the clutch on?
Chain looks too long. Could also be sticky pawls. Check correct chain length, remove clean, and regrease freehub.
Something is sticky, I’d try a bunch of lube first and see if that helps. The spot where the cage meets the parallelogram looks to be the root of the issue here
Your chain is not too long. Problem is the spring between cage and deraileur. Check if it’s rusty/needs lube/loose
Is it just me or is that wheel very out of true? Probably not the issue here but just wondering.
It amazes me how people are so confidently wrong on here. I’m a mechanic, your clutch needs a service. You can do it yourself if you are mechanically inclined or you can just take it to a shop and have them do it.
