Hello again,
I've examined it because you suspect the PSU.
I found a problem with the potentiometer used to separate the 5v current in the Meanwell power supply.

pressure on it gave random voltages. Usually 5v and under was going. I cleaned it with contact spray. I set 5V to 5.07v. I tested it like this for two days. For now, my problems have disappeared. I will continue to investigate again until it appears again.

Thanks for your help.
