Power switch does not work after update

[allsevast]

Hello!
I have problem after update TZTL15F to version 8.01:
after the update, the power button does not work when the system is loaded. He doesn't react at all. When turned off, it starts the system with power switch, but when the system boots, it no longer works. Modal window is not displayed when the power switch is clicked.
What can be done?

The problem is solved! I disconnected it from the power supply for several hours and everything worked.
