Good afternoon,

I'm having issues with my AdGuard container. Whenever there's a power outage or a restart of the Orange Pi, this container fails to start and shows the following log errors:

2024/08/14 11:00:17.129663 [info] AdGuard Home, version v0.108.0-a.950+cdf970fc

2024/08/14 11:00:17.144303 [fatal] initing dhcp: loading db: decoding db: invalid character '\x00' looking for beginning of value

The container keeps restarting and doesn't fully start.
A clean installation is needed for it to start properly.

-----------------------------

I found the problem but I don't know how to fix it.
I found that the leases.json list is buggy after you set a forced container shutdown problem.
When I entered the list I found that it has invalid characters @@@@@@@@@@@@@@@@
