Prime 2 restarts by itself when stopped

Hello everyone! I’ve had a problem with my Prime 2 for a few days. It turns on by itself when powered and restarts by itself when I turn it off. To turn it off completely I have to unplug it from the mains… Apart from that it seems to work perfectly once turned on. I’m running Engine DJ 3.4.0. Has anyone here ever had this problem?

I’ve reset the prime and formated the ssd. No change. But for some time transfers to SSD have been taking time (the ssd is in exFat format).

Thanks in advance for help
