Hi, I just upgraded from the Shield 2017 model with 2019 Tube version and in Kodi while trying to play any 4K it randomly stops and goes to Kodi homescreen , I know its not my wireless everything is at full speed and i have high end router Asus AX88U also does it on small sized 4k hdr 18gb

Yeah, you'll need the Pro for playing 4K without any problems.

The Shield TV is 32bit whereas the Pro is 64bit.

I'm currently testing the Shield TV but Kodi is crashing when playing 4K movies and you try and do something else like open bookmarks for them to be created.
