Windows 10 "updates" are constantly resetting my system every hour

My PC running Windows 10 is constantly hard resetting without warning to install updates. I have no problem installing updates normally, but obviously this isn't a situation I can live with. For some reason it only does it when I'm not using the PC, so that's at least a plus, but I run a media server from my PC as well which is always down due to it resetting.

I've tried pausing updates, setting active hours to only restart overnight, and even disabling the Windows Update service in services.msc but nothing seems to work.

[Here's the reliability monitor](https://imgur.com/yZjvBbC) from just this morning showing it "update" and reset multiple times.

Meanwhile [Windows Update says it's paused](https://imgur.com/9AlvSTc) and [shows the last update as July 7th](https://imgur.com/VTSW6eB).

I'm at my wits end here, for some reason these restarts also hang the computer half the time, and they're just so frequent. Has anyone run into this issue before?
