lightning community – Drive-closure of unknown channel: What do standing `Loaded from database` and the state AWAITING_UNILATERAL imply?

I observed that almost all of my lightning funds fail regardless of growing the price. It has been like this during the last two months.
Investigating this matter, I discovered an inactive channel within the output of listpeerchannels:

      }

I’ve no use of this channel and so I attempted to shut it,
sudo lightning-cli shut 881895f720246c99b6d4d9278510d37370344239e2e235f5e61c792ec495ea0e returned

{
   "code": -32602,
   "message": "id: Channel id not discovered: invalid token (see logs for particulars)"
}

During the last months I tried to learn from low charges by opening
lightning channels paying 2-3 sats/vbyte in charges. I did it over poor, intermittent connectivity, and
I used to be incessantly shutting down my node whereas the funding transaction was nonetheless unconfirmed.
I’ve non-public channels, 6 with ACINQ’s node and 1 with ALLNICE | TORQ.co.
From what I gathered from the values of last_stable_connection and timestamp (of the final state change)
the channel was force-closed earlier than it was locked-in with six confirmations. But,
it has been every week because the inactive channel and there
is no historical past of any transaction involving close_to_addr.

1. What does standing Loaded from database imply and why is the channel known as unknown?

2. Can it’s that my node was flagged by ACINQ node after this force-closure was triggered.
Would possibly this the reason for the failure of my funds?

3. Ought to I do something about it? How a lot sats am I going to free with this
force-closure?

4. How may I stop comparable points from occurring sooner or later?
