SIGSEGV (0xb) at pc=0x00007fa1b067ccbf, pid=7864, tid=0x00007fa1b1f36700

I can confirm the same behavior. I will also add that I've only seen it at launch time during the loading screen. This occurs on multiple Fedora 29 machines - some the crash is intermittent, the others 100% of time. Did not occur on Pre-Release 2. Added my log file as well.

Not the same addresses but the same error 0xb.
