Android on emmc keep freezing, why?

[kyllo]

Hello I have 4gb rock64 running following image of android on 16gb emmc:

Android 7.1.2 Stock Image [microSD Boot] [Rooted] [20171204]

It works pretty well sometimes however I keep getting constant freezes. These freezes happen when I am doing simple tasks like configuring rkmc settings or browsing play store for example. I have no choice but to unplug rock64 to get it working again it is very frustrating. What could be causing these freezes? As there be no reason that rock64 should be freezing like this especially when I'm only doing simple things that the hardware is more than capable of handling! 

Is there a better or more stable image than the one I'm using? I'm using rock64 as media player I just want nice stable rom that will allow me to do this but the constant freezing is driving me insane! I hope someone can help me! Thanks.
