After holding my bitcoin for a long time, i think i have somehow completly fucked up and they are gone. I have my bitcoin stored on a ledger and use ledger live. I have had a new pc recently so decided to install ledger live on my new pc. It dosn't show up my bitcoin account. So i went back to my original PC and ledger live still shows my bitcoin there. However when i try and make a tx i get an error message which i will provide in photos. Also when i connect my HW wallet to another bitcoin wallet like Electrum or Sparrow wallet they find absolutely nothing either, apart from a small account with some dust that ledger live also finds, which i sent the bitcoin from. I am gutted . For some reason in 2019 i sent my bitcoin to this address here 19NduweV3Hn8RXHFBQ32pKwCtbP5RBKwQw

ledger live on my old pc still still shows this account as mine as you can see in the photo. Yet dosn't let me send any bitcoin from this address. My life savings gone on some dumb error on my part.
The only saving grace i can think of. Is that this account is a 'secret account' where you can add an extra word to your 24 word pass phrase. Which i do remember setting it up as i have it wrote down. However i am not sure i ever sent bitcoin to this. The problem is i had to recently buy a new ledger hw wallet because of the screen dimming issue on my old one. So maybe i need to set up the 25th secret word on the device propely? and by some miracle the bitcoin is in that account. i dont know how though?
And i havn't input the 24 word key into my new device wrong because this key has some shit coins on it which it found. I know its only 1.7ish bitcoin, but its basically most of my life savings. Thinking i had done everything right buying a hw wallet and storing my coins myself and now its gone is heart breaking. I know this is on me, somehwere i have fucked up and dont know how but still.

Any advice much appreciated

i am sorry i am not sure how to add images.
