I had the same problem, and probably @Fen had the same here: HAOS no longer booting
I’m using VirtualBox, and ended up with installing my image on other hardware. Luckily I make a network backup of the entire image, on my NAS, every time I upgrade, so only lost 3 days of statistics and have been living in the dark for some time 
The thing that started the problem for me, was install of some Coral-stick drivers.
Sorry I cant offer some help, but perhaps raising some awareness can help you get to a solution - Really hope you will get it solved.
But TGIF and we have a bit more spare time
