MattStH,
When the Launcher crashes, before you dismiss the crash dialog, there should be a crash .dmp file in the same folder as the log. Please can you upload this too as your logs are cut off and don’t contain the crash information, thanks.
Also some people have reported a crash in Windows 10 due to Lavasoft webcompanion being installed and/or the presence of the dll/registry settings, more info can be found here
