U2722DE, no USB-C signal from your device #9

I have a similar problem. After U2722DE goes to sleep, is says no that it can't detect signal on USB-C. When I unplug U2722DE and shutdown MacBook, go home, and next day it works. I updated MacBook. I saw on some forum that also some Dell monitor software could cause problem, but I have uninstalled it a week ago. USB-C cable is not the problem. Earlier U2722DE was afternoon flickering, so I had to uncheck this adaptive colors on my MacBook. And now this second problem. On other Asus monitor connected with HDMI., I don't have any problems.
