Subscribed Workshop items stop downloading

Hello, I started having problems downloading items from the workshop. I see the item being downloaded in the window at the bottom of the screen, then it stops, stays like that a few seconds and disappears. When I restart Gmod I see it is still at the percentage it has stopped before, again stays like that for a while and disappears. tried restarting the computer and the situation didn’t change. The file doesn’t appear in the addons folder while it’s being downloaded, so I can’t reset the download. Is there anything I can do?
