Our channel force closure is still pending but I am hopeful that it will be resolved soon as it has only been about a week.
Keep an eye on the status of the force close and check to make sure it happens on schedule. If it is not happening on schedule and it was initiated from your node, you can reach out to the operator of LNBig-42 and ask them to initiate a force-close from their side.
Otherwise it was initiated from their node and you may be able to use this: https://www.reddit.com/r/lightningnetwork/comments/nblv5d/can_you_forceclose_a_channel_that_is_already/ to force close from your side, but I cannot be sure because in this thread the channel close was mutual.
This was likely caused by the same HTLC expiration default setting observed in this question posted a few days ago:
Automatic force closure and on chain settlement of expired HTLC
