WIN.  Designer crashes complete when starting a new doc or open an existing doc. I have already installed it new but without impact

 

It works proper on MAC

Hello

I need your help

A monitor hangs on a sloping roof.

Now, nature pictures should be portrayed as looking out of a skylight.

I can not find a way to do that in Affinity Photo

I'm grateful for any help

 

Thank you very much
