Why does Factory Image fail to boot after all application images are corrupted?

Prior to Intel® Quartus® Prime Pro Edition Software v21.1, if all application images fail to load and execute, then the system will ultimately load and execute the factory DCMF image.  However, due to an error in the Intel® Quartus® Prime Pro Edition Software v21.1, the system will fail to boot the factory image.
