The new PM visiting the monarch isn't just a formality. She can tell the PM "I don't like you, and I refuse. Go away." And then they need to find a new PM candidate.
The Head of State retains the power to dissolve parliament and call for new elections in many European countries today, whether that Head of State is a monarch or a mostly powerless president.
Though the fact that you called elections does not mean the PM you dislike will also fall in disfavour. They could come back with a larger majority and make things worse. The Head of State would usually use this power when the population would likely vote this leader out for their deficiencies (whether real or imagined).
Or when necessary for exigent circumstances, like inability to form a Government. Though in Belgium it looks like Government is optional...
