For flash memory which only burns STM32WB55CGU6 series chips, one sector is locked and cannot be read or written. According to the chip manuals, there are errors in mass erase and programming. How to solve it?

The STM32WB55xx devices embed an Arm ®(a) CPU1 Cortex ® -M4 core.

I use this chip manual.

I operate strictly according to the chip manual, but all of them have errors in reading, writing and erasing a sector.

the flash meomory address range:​0x0800 000-0x080f ffff,But when I use burning tool to burn, there is an error in this address 0x080f 6000, reading and writing all report this address error, the following areas can not read and write, using mass erase also report errors; when using j-link burning, erase blank chiperase, erase sector succeeds, erase chip error.
