I had the same problem with Launcher crashing my computer. I spent hours trying to understand why Launcher would suddenly start crashing my Windows 10 Professional system. Turned out it was some new conflict with Avast Professional antivirus. I've used Avast for the past five years without issue, but the latest update must have created issues with Launcher and probably other programs as well. I did try going back to my last restore point but that didn't fix the issue. Finally I uninstalled Avast Professional and went to Windows Defender. Everything seems to work now so I've created a new restore point and I'm keeping my fingers crossed.
Oh, and the Avast/Launcher issue wouldn't let me shut down or restart the computer once I attempted to launch a DXLab application. My only resort was to force a shutdown.
