Problem load sketch CJMCU TF ATMEGA32U4 #5

[gianfelicevincenzo]

Hi, I ordered this CJMCU TF ATMEGA32U4 controller (leonardo) on Aliexpress

The problem lies in loading the sketches. Nothing ever loads. Every time I get the error "ttyACM0 Permission Denied"

I have already done all the necessary checks. my user was added to the dialout group, I also set all the permissions on ttyACM0 via chmod but nothing. After various searches I read that before loading the code you must hold down the button on the card. I did it, even part of the loading starts but shortly after it stops with the error "butterfly_recv(): programmer is not responding"

Here is more information regarding this controller from arduino ide:

How is it possible? I really appreciate your help because I don't know where to turn anymore, thanks.
