Hello i’ve found some similar case here but on solution inside the thread Pending Channel stuck and error message at bumping fee - #2 by StuPleb
I got 2 utxos in my core lightning onchain wallet 1m and 50k. I tried to open 1m channel and than get his error

I’ve tried once again with another node and got pretty much the same error
I have in my UIs (both CLN and RTL) two channel with pending state and with transaction Ids that are not in the memepool. I see my ballance 1 050 000 sats but when I try to move it get an error 0 balance available
