I tried to open a channel but it is pending forever

[kalkulusrampage]

There is a onchain transaction to open a channel that matches the id of the pending channel in mempoolspace but have different sats amount. When I click "view in blockexplorer" in the onchain transaction or in the "pending" channel of the lighting channels section, the output of mempool.space is the same:

"Transaction not found.
Waiting for it to appear in the mempool..."

I tried copying the "raw tx hex" of the onchain transaction to open the channel and publishing it into:

https://mempool.space/tx/push

But the output was this error:

"bad-txns-inputs-missingorspent"

Then I tried to import the seed and channel backup to a second phone. In this case the onchain transaction to open the channel is missing but there is a small transaction with the "sweep" label (when I click to view in blockexplorer "transaction is not found"). The lighting channels section shows this:

Then I tried to import just the seed in the second phone and I recovered the amount of the onchain transaction to open a channel but the founds of the "pending" channel are still missing.
