My M5Stack CoreS3 suddenly stopped working. Here is the current situation:

Screen is completely black
When I press the power button, it turns on for a moment but immediately shuts off
USB is recognized for just a moment when power button is held, then disappears
RST button long press does not enter download mode
Separating Core from Body and waiting several minutes did not help
Serial monitor shows nothing

Has anyone experienced this and recovered it? Any suggestions would be appreciated.
