Bitcoin Core Wallet is stuck and cannot send money

I have a wallet made in 2013, and it has a considerable amount of money in it, so I would like to get it. I restored it to Bitcoin Core on several separate machines with full nodes each. I didn’t set a passphrase when I created this, but now it asks for a passphrase when I try to perform a transaction. On one machine only, the Bitcoin CLI does not prompt for a passphrase.

Also, I cannot give the private key so that it can be imported into electrum. It will ask for a passphrase or say the private key is unknown. When I run dumpwallet it doesn’t seem to find a suitable private key to import into electrum. I might not know which one, so any help on that would be appreciated.

Looking at the transaction that rebroadcasts them shows that there are bad-txns-nonstandard-inputs (code -26). This may be caused by dust. The minimum amount for a single input is 868 sats. I tried to join sendmany, but when I join I see that there is a JSON parsing error. I see something similar when I try to specify the input for the sendmany “” {“walletaddress”: amountofdust} transaction.

We would appreciate your cooperation. Thank you for your support.
