MacBook Pro A2779 820-02841 gets stuck on a black screen after a few seconds of the Apple logo

My MacBook Pro A2779 820-02841 powers on, but the screen only displays for a few seconds, showing the Apple logo and the loading bar, while the motherboard remains powered on. The strange thing is that when I enter recovery mode, the screen displays without issue, but upon entering the recovery options, it again shows the Apple logo and then immediately goes black.

The problem started suddenly. There is no corrosion, and the voltages to the display appear to be correct.

What about external video?

You may force it disconnecting internal LCD.
If there is no data to save, you can try DFU restore.

When connected to an external monitor, it displays a secondary screen image.

I have successfully restored it twice using DFU. However, the problem persists.

"When connected to an external monitor, it displays a secondary screen image"
Main screen should appear when you close the lid.

I already tried turning it on without the lid sensor, but the problem persists.
I managed to get the monitor to detect the main screen, and according to diagnostic mode, the screen is being detected without issue.
The device turns on, displays the Apple logo, and once it reaches the lock screen, the screen goes completely black.

If external monitor also gets black, there should be a problem with graphics part of CPU.
You only get image until dedicated graphics driver is loaded.

As you don't have data to save, check what happens with Linux, or Windows.

How can I install Linux or Windows natively on an M2 MAC?

Using a pendrive.
You can first try a Live distribution, which usually comes with lot of system tools; including storage tests.
