Nodemon the `punycode` module is deprecated in node js 21

[DeniroBlack]

Hi. I upgrade my local node js from 20 to 21. After that, nodemon stopped working. Will it be fixed? Or can you tell me how I can fix it on my own?

App without nodeman works good, but without nodeman I can't debugging 😔

Can you run and paste the results of this command:

npm ls punycode

nodemon doesn't use or include punycode.
