Motherboard turns on and off when plugged

Hi everyone, I recently bought a J3455-ITX motherboard.

When I plug the computer in the socket, however, it immediately turns off, and then after a couple of seconds, it turns off by itself.

In the BIOS I found something like "automatic turn on when sudden power outrage" (sorry I don't remember the exact name) and it was set to false. When I set it to true, the computer turns on the moment I plug it in the wall, without turning off.

I would just like the computer not to to anything when I plug it in the socket, like the other computers I have. Is it possible to do something about it?

Online I found similar issues for example https://forum.asrock.com/forum_posts.asp?TID=7512
