Unable to select the target board "Current board target is invalid !"
Figured out that there is an error in the new STM32CubeMX (V5.5) tool that it does not generate the linker script file(maybe because of anti-virus tool deleting that file), so that is why it is not able to find the required path. To solve this problem I actually installed the SMT32CubeMX as a plugin to the Systems Workbench IDE and then was able to generate the required files and compile the project correctly.
