antivirus – Bypass Windows Defender

I am currently working on my own Rat and I got a FUD reverse shell.
But I have a problem…
I can only connect to the shell with nectat. But I want to use Meterpreter because I can do more things with it.

If I start a listener on metasploit I get a Connection and a Shell but if I move the session to the background and connect again I don’t get the connection again.

So I don’t want to use the code anymore and that’s why I am wondering if there is another way to bypass the windows defender , or make it FUD with a meterpreter exe.

I tried codes like VeilEvasion or unicorn but these are outdated and don’t work anymore…

I hope you can help me
