Macbook Pro sleeping by itself when using USB-C Digital AV Multiport Adapter

From some weeks to now, my Macbook Pro started to sleep by itself, randomly. The machine turns its screens off and I have to disconnect all cables and press power to awake.

I already tried to reinstall macOS from scratch, ran EtreCheckPro, did a lot of tests, and could isolate the adapter as the potential responsible for the fault.

There's no visible damage in the adapter and I wonder if that couldn't be a software compatibility fault. Here in Brazil, this adapter is very expensive (> US$135) and I couldn't risk buying a new one and getting the same result.

Is someone more passing by this situation?

macOS Monterey 12.4 (21F79)

I don't quite understand; all Macs will sleep unless you takes steps to prevent it or extend the sleep period.

An action such as rattling the mouse, pressing the space bar, momentarily pressing the power button and etc. will wake them.

Because of that I used the word "randomly".

The machine randomly, suddenly, simply goes to sleep without any reason. As I said, I did all possible tests, like uninstalling suspect apps, booting in safe mode, everything. Including disabling the power-saving options, hot corners, etc.

Until now, nothing but stop using the (original Apple) adapter works
