Try STM32CubeProgrammer. Can you do a full chip erase? If not, post error message.
The chip needs to be in bootloader mode to respond on USB DFU. Hold BOOT0 high during reset.

This is the second time it has happened to me. Some people talk about "Fake Chips". How to know if my STM32 Chips are Fake?
