Among other reasons, other than performance, there's staying few time than default FMC logic allows to at the cruise alt you've set, or having wrong Temperature predictions for that cruise alt...

Also high / low "barber pole" bands too close...

Bill Bulfer's guide:"FMC predicts the aircraft cannot reach the new CRZ ALT due to performance limitations or no cruise time possible at entered CRZ ALT."

But it might be a Zibo prgramming bug too:

 

In my glider I often get that message 😞  It spoils my tasks so many times that sometimes I whish I had a prop and a noise producer making it turn enough for the glider to climb....
