Can't read or erase flash anymore NUCLEO-WB15CC

[tester]

I am working with a NUCLEO-WB15CC, and it seems that I can't read or write anymore. When I connect via ST-Link in STM32CubeProgrammer (v2.14.0) I just get

Error: Data read failed

When I try to read registers, I get the same error.

I also can't erase the chip:

Error: Mass erase operation failed.Please verify flash protection

RDP option byte is AA, so that can't be the problem.

For write protection, I don't really remember what the default values was, but they are: 0xff, 0x0, 0xff, 0x0,

I can still see target information in Programmer but nothing else seems to work, have I bricked the chip?

Edit: I noticed I also can't read registers via the CLI, so maybe it's not a bug in STM32CubeProgrammer.

This is the command I used:

STM32_Programmer_CLI.exe" -c port=SWD -r32 0x08000000 0x4

Which results in

Error: failed to read the requested memory content

Read protection seems to be disabled:

Here are all the option bytes:

OPTION BYTES BANK: 0

   Read Out Protection:

     RDP          : 0xAA (Level 0, no protection)

   BOR Level:

     BOR_LEV      : 0x0 (BOR Level 0 reset level threshold is around 1.7 V)

   User Configuration:

     nBOOT0       : 0x1 (nBOOT0=1)
     nBOOT1       : 0x1 (Boot from code area if BOOT0=0 otherwise system Flash)
     nSWBOOT0     : 0x0 (BOOT0 taken from the option bit nBOOT0)
     SRAM2RST     : 0x1 (SRAM2 is not erased when a system reset occurs)
     SRAM2PE      : 0x1 (SRAM2 parity check disable)

     IWDGSW       : 0x1 (Software independent watchdog)
     GPIO_MODE_PB11: 0x1 (If RESET_MODE_PB11 = 0: Standard GPIO pad functionality, Only internal RESET possible. If RESET_MODE_PB11 = 1: Bidirectional reset, NRST pin configured in reset input/output mode (default mode), GPIO functionality is not available on PB11.)
     RESET_MODE_PB11: 0x1 (If GPIO_MODE_PB11 = 0: Reset input only, a low level on the NRST pin generates system reset, internal RESET not propagated to the NSRT pin. If GPIO_MODE_PB11 = 1: Bidirectional reset, NRST pin configured in reset input/output mode (default mode).)
     IRH          : 0x1 (Internal resets drives NRST pin low until it is seen as low level.)

   ESE:

     ESE          : 0x1 (Security enabled)

   PCROP Protection:

     PCROP1A_END  : 0x0  (0x8000400)

I "fixed" this by running this command to reset the board to factory settings:

STM32_Programmer_CLI.exe -c port=SWD reset=HWrst -w32 0x5800040c 0x00008000
