Hello @Nnabb.1 ,

This issue is fixed in the STM32CubeProgrammer 2.16.0.

STM32CubeProgrammer 2.16.0 released - STMicroelectronics Community

"162313 [STM32G031GU6] Wrong flash memory size of 63 Kbytes instead of 16 Kbytes."

First, I advise you to remove all older versions of STM32cubeProgrammer, and make sure that you are using the latest release.

Then, let me know whether the problem here persists or not.
