[BUG] Sometimes the printer is freezing

[anno0]

Bug Description

I print from SD card. Sometimes the printer is freezing. It beeps a few times in a higher frequency and the print head goes up. This happens if I want to start a new print.

Steps to Reproduce

1. The printer cools down from the last print. The bed temperature is 40 °C and the print head temperature > 50 °C. So the fan is running.
2. I have selected the print menu and have selected a model to print.
3. Start the print
4. After a few seconds it beeps in a higher frequency, the print head goes up and holds it current temperature. Well this is displayed in the displayed.

Expected behavior: I would expect that the print is started without error

Actual behavior: Sometimes this bug effects that I have to power off/on the printer.

Additional Information:

Anycubic MEGA X with DGUS clone display.
Release 1.5.2
