Sats are stuck in a limbo after a couterparty force closed [sweep at "stage": 1]

[Gabrio2]

Background

I received a force closed with a limbo. The limbo at the beginning was 1,906,337 sats
Now is "only" 92,430 (the most part I have already received few days later the closing channel
with many many little transactions each time)
I'm looking for some guidance how to sweep the remaining 92,430 sats to my on-chain wallet.
Thanks in advance for your time.

My environment

• LND 0.18.2-beta commit=v0.18.2-beta
• operating system: Ubuntu 20.04.6 LTS
• Bitcoin Core v27.1.0 no prune, fully synced

Expected behavior

Funds to appear in the wallet after maturity

Actual behavior

Below is the output of (I guess) the 2 most relevant commands
