Additional information and/or screenshots

Previously, running it as a service worked fine, but recently, after a power outage, I tried to manually restart AdguardHome and encountered these issues. Of course, it could be due to my lack of familiarity with FreeBSD, but the panic is undoubtedly a BUG.
