HomeAssistant OS missing addons

Hello,
As you can see on the screenshot I see too few addons in the supervisor menu.

I have already tried deleting the repository and adding it again.
I also tried supervisor repair. The procedure was successful, but the addons remained few.
I will be very happy if someone can advise me how to solve this issue. I’m running hassos on Hyper-V VM. Here some info about my system

Hello, it seems that you have a problem with the supervisor as in the config you provided, there is a “unknown error” at the level of the supervisor (and it is very difficult to determine the solution for a unknown error)… You should have something like this for the supervisor chapter:

One path should be to analyze the system log and see if additional info could be found about this error…
