The specific problem here is that Charles has done less than zero to endear himself to the public. So far his most obvious interactions have all been "Look at me! I'm king now!"
For example - this silly little exercise. And his request that there should be portraits of him in school and public offices.
This will have been filtered through courtiers saying "I'm really not convinced that's a good idea, your majesty." So these public proofs of his kingness seems very important to him.
Meanwhile much of the country is starving or in debt, shops and businesses are closing, and infrastructure is crumbling.
I'm defending neither the institution of the monarchy nor Charles as a person, but this particular exercise is standard, not a whim of his. Each monarch has their own personal cypher, and has had for years. https://www.youtube.com/watch?v=L_ZL7H7WCzM
And reflecting that cypher in the gov.uk branding was not Charles's choice.

It's not a good look.
