Epic games launcher not working since Windows 10

Sure thing. Here is the log file.

Since you’ve asked I’ve payed closer attention to the behavior.
I can reproduce this issue at any given time actually.

I open a .uproject file. Some time after the engine has finished loading, the launcher, which was startet in the background when opening the .uproject file, shows me the following message:

53827-error_when_opening_uproject_file.png

Clicking the “retry” button, alwas brings me back to the same message. As soon as I click the “ok” button I’ll get a “please wait” message. If I have a look in the TaskManager the launcher.exe has become inactive and does not react anymore.
The launcher log gets stuck as well at a very specific point which I have marked within the file with four exclamation points at the timestamp [2015.08.12-10.37.35:311]
At that point I usually kill the task since it does not react. However if you give it enough time, like 30-60 seconds, you will be presented with the launcher login mask.
The log timestamp doesn’t seem to be accurate at that point since the entry I marked and the next one are sepereated by mereley miliseconds.

However the launcher does not excactly crash as originally stated, sorry for that.
