Please provide several examples of input that should match and input that should not match, with a brief explanation of each. – Bohemian Jun 18 '23 at 07:26

Maybe, you might just want to list the chars that you wish in a [] and test it. Maybe, a simple expression like this would be desired for you and you could work on it:
^([?!"'~&%$*@#0-^@9]+)$
You might want to use this tool and design an expression that you wish, then test it with real samples and maybe change it as you wish.
You can also use an online visualizer to view how your expression would work:
