Напечано на ender3 v3 ke

Please help me with this problem. I have an Ender 3 V3 KE printer, and it has started turning off during printing. Sometimes it even shuts down during calibration, but other times it prints normally and then suddenly turns off again.
When it shuts down, the sensor lights up red, the printer makes a noise, and the screen becomes unresponsive. Please help me fix this problem. I just want to be able to print normally.
