Screen freezes and restarts in loop

Good morning everyone,
after a month of inactivity I turned my P1P back on but I realized that it was no longer connecting to BambuStudio on my Mac, I then realized that the display (or the software) turns off and restarts in a loop every 4 seconds.
I have already tried turning it off and on again several times but the problem remains.
In the few seconds the display sometimes works, sometimes it remains blocked… if I don’t touch anything it goes into restart in loop

I also tried removing the supplied SD card (which I never use) but the problem remain

What can I do? Thanks for your help
