Problems with xposed using kodi as homescreen.

I have a few rooted boxes and I use xposed to use spmc as my homescreen. My issue is that after about a few months of use the device will just randomly start loading to a grey screen. It is at this point that I have to mess around with the voice control button on the remote and unplug the wifi etc to get it back to the main amazon screen then force stop kodi and relaunch it. I am not sure what causes this issue but it can be quite a hassle getting the amazon screen back when I use kodi as the default launcher and the screen gets stuck on this grey screen. I've even had to do a restore on some, luckily i have rbox bootloader on my boxes or I would probably never be able to get back to it. Does anyone have this issue and know of a remedy?
