Ok, I have to say that.
 
Today I tested something and used a new fresh installed SD-card Armbian_23.02.2_Nanopim4v2_bullseye_current_5.15.93_minimal (image from above). And armbian-config was able to install over apt
 
apt update && apt upgrade -y apt install armbian-config
Cheers

There are some older threads where people noticed it too, myself included 
 
Would you like to participate in testing of a possible cure workaround for those issues?
Here is the image build off the master with RAM settings tweaked a bit: https://drive.google.com/open?id=1H4K-1sBUttbeHZUaE_J-t-P5cjYiqPU7 
If you want to build the image yourself you can use this branch of Armbian build system: https://github.com/armbian/build/tree/nanopi-m4v2-stability-fix
 
I have mine restarted several times with those settings and I see no crashes on boot/reboot but it certainly needs some longer uptime testing to be deemed successful.

It is running. The log isn't full with Hex-code. Thank!
