UI issue on FireTv OS6 - Android 7.1 - Xamarin.Forms v4.8.0.1451

Just a shot in the dark as I'm struggling to kill a random UI freezing issue with the versions listed above. We are requesting changes to the UI but the UI isn't reacting. When we back out of the frozen page the app completely freezes and requires a restart to get working again. This typically takes a couple of hours to occur.

I've also seen the garbage start collection and get stuck on the GC_Bridge (using both tarjan and new bridge algorithms). I suspect we have something that is blocking the UI thread, but I can't seem to narrow down what that might be. Everything I programmatically pass up to the UI thread is logged at start, stop and error and nothing appears to be stopping mid flow. Anyone got any ideas or pointers as to what I can do to get some insight on what might be occurring in the UI thread?

Thanks
