The bug was triggered when the software attempted to migrate an unnamed legacy wallet.dat file stored in a custom wallet directory while pruning was enabled. In these specific conditions, the cleanup logic mistakenly deleted the entire wallet directory, potentially causing fund loss. Developers withdrew the affected binary files and advised users not to use the migration tool until a patched version was released.
