I know this is stupid but please here me out so you don't make the same mistake. I was tryi'g to build a multisig setup a couple years ago, I was such a genious that I used the same (single) wallet to set it up on Sparrow, using three diffrent account XPUBs from the wallet, so I was able to create the magnificent wallet in which my money is loked-up now using three xpubs. It's locked up bc I sent some to it as a try but now after 2 years that I thought the money was safe just find out I was wrong. I tried to sign a TX out with the hardware wallet it's saying 'invalide PSBT' whatever that means. Now, I know it's embarassing to ask for help like that, but I need help sorting this ouyy. Maybe I am wrong it's not locked but experties isn't high enough to know.
