Display deactivated on OnePlus 7T after actualisation

I am having a OnePlus 7T and until yesterday /e/OS worked fine. After an actualisation I did yesterday the display does not react, like it is blocked. I installed lineagesOS and everything is fine. A totally new installation afterwards of /e/OS is the same like before the lineageos installation. I do not get further than the welcome screen as there is no reaction to the ‘continue’-button. I cannot turn the device off as I cannot choose ‘reboot’ or ‘halt’, when I press the power-button.

How can or do I have to activate the display?

Hi @linfiets welcome to the /e/ forum.

I cannot offer the solution, but just to cross reference
