CPU spikes to 79-100% usage when navigating in menus after restart

I’m using an RG34XX. I’ve recently installed MUOS 2601.1 onto a new device, but now whenever I restart the device there is a period of a minute or so where any inputs causes CPU usage to spike to absurd levels. This causes menuing to be incredibly slow or to input multiple times.

The issue goes away for an unknown reason after a while, however it is a hassle to have to deal with this whenever I start my device

Does anyone have any idea what’s going on?
