EEPROM erase not working on STM32L072 with STM32CubeProgrammer v2.13.0

[edurohr]

The EEPROM erase function doesn't seem to work with STM32CubeProgrammer v2.13.0, but works fine with STM32CubeProgrammer v2.11.0. Although v2.13.0 reports that the erase worked, the content of the EEPROM remains unaltered. Furthermore, something else in the flash microcontroller seems to be altered. I tried with multiple PCs, boards, and STLINK-V3MINIE programmers. The issue appears both on GUI and CLI versions.

There are 2 obvious differences in the logs below:
1) Time difference: v2.11.0 takes around 10s, while v2.13.0 only takes around 1s
2) v2.13.0 periodically reports this: "fail @0x00000001"

v2.11.0:
