PSA: Adding -shareArchive to your initial command prompt line item on load automatically crashes the game before the launcher loads.

The result of removing this -command will cause undesired effects (crash your game) if you are also running a real-time virus system scan or system performance monitoring software.
Happy Sept 20th patch day!
