It sounds like the issue may be related to some formatting or symbols in your CSV file rather than the words themselves. The angle brackets ("<" and ">") and asterisks ("*") aren’t part of a valid BIP39 seed phrase, which is likely causing the checksum errors. Try removing any symbols, such as brackets or asterisks, from the seed phrases and see if that resolves the issue.
If the problem persists, the words could be in the wrong order. Since BTCRecover didn’t help reorder them, it may still be worth trying different combinations manually or using tools designed to brute-force different seed orders. Make sure the seed is exactly 24 words, as BIP39 requires a specific word count for the checksum to pass. Good luck!
