Hello. I just wanted to share my experience with this issue too.
I had exactly the same issue with a Tanix clone, in my case it's a cheap chinese android box with an H6 called the Z3 (https://androidpc.es/a95x-z3-android-box/). I've used 11.0.3 for a yer and suffered of this too. Tried several ways to log something during crash but it was impossible.
After updating to 12.0.1, not only this issue disappeared but there's a huge performance improvement. Before I had to force my display to 720p in order to watch without lag, but now I can go up to 1080 and it works perfectly.
Thanks to all the devs working on it!
