When launching the game in any way the UDK.exe loads for 1-2 seconds, then just stops loading at all and the computer memory will not change at all from that on. The splash screen will not show up and only sometimes a log is created, which is empty however. Changing the priority of the task has no effect. Killing the task reselects launcher just fine. Launcher itself is also working fine. I tried reseting, verifying and reinstalling, but none fixed it.
The issue is there since yesterday (6.10.2018), the day before i could still play. Only things that should have changed are that i moved to another city, use a new router and deinstalled AVGTuneUp.
