Hello,
From waht I read, I think Quartus does not have enough info to conclude anything. In the SDC file you might need to update/correct your clock timing constraints. Best Regards, Johi.- Mark as New

You should have a .sdc file that includes timing constraints for your design, which is listed in the screenshot, so I'm not sure if you got that .sdc from somewhere else or created it yourself. See the Quartus handbook and online trainings like this for details:
