Another .tar test update this time testing 2160p 420,10bit video output.
The main aim of this release is to use 420,10bit for all 2160p video modes if...
Kodi Settings > System > AMLogic > Enable autoswitching Chroma & Bit Depth is > ON
The Kodi GUI should be left at a 1080p 50 or 60Hz Resolution so all 1080p picture output (inc. Kodi's GUI) is upscaled by a 4K TV using it's superior picture upscaling hardware.
4K HDR Sony owners have been complaining about 444,10bit and having to put their TV's into a 'PC' mode to use such settings and then losing a bunch of video processing modes in the process.
We do not need to use the PC or Gaming - subsampling mode of 444 for Kodi video playback usage.
4K HDR Blurays are encoded with 420,10bit subsampling and bit depths anyway.

There is a bunch of info about Chroma Subsampling here:
Chroma Subsampling: 4:4:4 vs 4:2:2 vs 4:2:0
As for Freezing - not all AMLogic boxes are created equal, the MINIX U9 I use for testing very rarely get over 55 Degrees C.
Disable GPU Overclocking would be my very first suggestion and the second would be do some DIY Chipset cooling mods.
