I tried different things even uninstall and reinstall STM32CubeIDE but nothing works.

What finally works for me was select "ST-LINK (OpenOCD)" instead of "ST-LINK (ST-LINK GDB Server)" in Debug Probe in "Ält/Run/Debug configuration/Debugger".

Besides, after that I was able to go back to "ST-LINK (ST-LINK GDB Server)".

What is your device id shown by st link and what datasheet say?

Is it genuine device?

OpenOCD will flash it but GDB wont :)
