Hi Lea!
1. I found spacedeskService in services.msc but it was stuck in the process of stopping and could I could not start or stop it.
2. The connection was more stable yesterday and I had a hard time catching the issue (it did happen still, but with hours between) but today the display is turned off after a few minutes. I’ve attached the requested zip file in this post.
The android version is 7.1.1 and I am using reverse usb tethering for the internet connection.
