EDIT: The problem has been solved by chosing the integrated Intel graphic chip to use for the Launcher, instead of the Nvidia card. Appearently there is a problem with the latest Nvidia driver that is causing the Launcher to not start properly.
Thanks to VictorLerp for his helpful suggestion.
I just reinstalled windows 10 (64bit) and downloaded the latest version of the Launcher. Now, after installing, whenever I try to start the launcher it just “flickers” as if the launcher is starting and closing every second.
It’s running in the taskmanager but only in the background tasks. After a while it asks me to install the prerequisites, but just goes back into flickering mode when I click the ok / install button.
This has never happened before, and I just used the Launcher before the fresh windows install this morning, so it can’t be anything on my system side.
It’s a huge problem because I can’t install unreal engine and our teams whole development has to stop because of this…
I can’t attach the logs because I am not allowed to upload .txt files (why?) and the log is too long to paste it into the comment section. So I uploaded them to Google Drive:
The logs throw out a LOT of errors, which never happened before.
