Problem installing a plugin

So I have problem installing a Vault plugin needed for MobHeads. I also have problem installing plugin Ridables. I tried solving it myself but I don't really know how too, I tried eveyrthing.

Here's also my log but I'm not sure you might see the detected problems https://mclo.gs/WvYrUis

Well I am having trouble with installing Vault as well. It shows me the green check but then it immideatly diapears.

Also can't find Ridables under files so i don't know how to remove it.

I'm trying but whenever i start the queue I somehow get up from computer right before it starts and then it shuts down.

I know that, but I'm not there when it appears and I miss it.
