Bitcoin core wallet migration bug can delete your wallet directory resulting in loss of funds

Bitcoin Core wallet migration bug: Bitcoin Core posted a notice of a bug in the legacy wallet migration feature in versions 30.0 and 30.1. Users of a Bitcoin Core legacy wallet who use an unnamed wallet, had not previously migrated their wallet to a descriptor wallet, and who attempt a migration in these versions, could, if the migration fails, have their wallet directory deleted, potentially resulting in a loss of funds. Wallet users should not attempt wallet migrations using the GUI or RPC until v30.2 is released (see Bitcoin Core 30.2rc1 below). Users of features other than legacy wallet migration can continue to use these Bitcoin Core versions as normal.
