Nice @pillar found this https://damus.io/key/

Hexadecimal numbers use 1-9 and the characters a,b,c,d,e,f (there are a total of 16 symbols, hence the name hexadecimal).

As you can verify yourself by looking back at your key, it contains non-hex symbols. Hence, you can realize that what you have there is not a hex number of length 64.

I would suggest you to search how can you convert your npub to a hex number and try again.
