Switch OLED bricked after game crash?

[u/15-4031TCX]

I was playing Tears of the Kingdom this morning on my Switch OLED model when I was suddenly stuck on a loading screen. The loading animation was still working, and I was still able to press A to see the next tip, but the progress bar had stopped advancing completely for quite a few minutes. I was also unable to use the home button to return to home page and force quit the game.

So I decided to manually restart the Switch by holding power button then press it again. This procedure worked out fine and I was soon back on my home page. However, I made the stupid mistake of opening Tears of the Kingdom again, thinking I had fixed the problem.

This prompted an error message immediately, saying an error had occurred and I should restart my Switch again by holding the power button.

As soon as I started holding the power button, my Switch got stuck into a black screen and refuses to be turned on again. The battery is not drained as my Switch still has battery when the game crashed (it was not at a high level, but not too low either; no low battery warning). No charging logo appeared when plugging in/docking the Switch.

I have tried:

1. Hard restart by holding the power button, waiting a few second, press power button again. It never worked. I have tried this both with the Switch plugged in and unplugged.

   1. Going into maintenance mode by holding volume +/- buttons and power button. Did not work after multiple tries.

2. Repeated the above steps with both Tears of the Kingdom cartridge and MicroSD card removed. Did not work.

3. Tried to see if the Switch is actually turned on, but stuck on black screen (though I did not observe visible backlight). I tested this by docking my switch and trying to see if I can wirelessly connect my Joy-con. I could not.

I am now wondering if this problem is fixable, whether it reflected hardware/more severe damage, or if I should just opt for a Switch 2. My Switch was running perfectly fine before all this happened and still felt very new.
