I got this from Eassus.
"Upon the 'Preparing automatic repair' window, press-and-hold Power button 3 times to forcefully shut down the machine. The system will enter boot repair page after 2-3 times of reboot, choose Troubleshoot, then go on to Refresh PC or Reset PC."
Of course, some data may be gone, and you may come across some problems but you can read the entire article here: https://www.easeus.com/resource/fix-preparing-automatic-repair-loop.html
