I've updated Kali Linux recently to Version "2022.2" so I guess some update is causing this bug:

Using the following command with netcat sudo rlwrap nc -nlvp 443 without extra flags and I got a reserve shell connection successfully but I'm experiencing that when trying to send a command I have to press enter twice and the command show as illustrated in the image attached with a ^M character image

sudo rlwrap nc -nlvp <port> <shell_cmd>

... starts a server - why would you want to use rlwrap there?? - it won't do anything remotely useful (or even observable), as the server doesn't expect input from your terminal.

It is on the client side, i.e. when connecting with nc localhost <port> where rlwrap can be useful:

  rlwrap -p -S"shell > " nc  localhost <port>

Closing as rlwrap cannot possibly be the cause of your problem.
