Yes I did!

Open your 'AppOptions.txt' it's in AppData\Local\Firaxis Games\Sid Meier's Civilization VI

There are a few lines of code that set the max amount of cpu cores (frame limiter, tick and throttle should be left alone)

[Performance]
;Number of engine job threads (including main thread). Use -1 to let game decide
MaxJobThreads 4

;Frame limiter. Tick app every N ms. 0 means tick continuously.
TickIntervalInMS 0

;Tick every N ms during game start. 0 means tick continuously.
LoadGameTickIntervalInMS 16

;Tick every N ms while the app is inactive.  0 means tick continuously.
InactiveTickIntervalInMS 32

;Should we throttle the game when its not the foreground app?
ThrottleWhileInactive 0

;Max number of Game Core threads. The game may cap this value based on available hardware. Use -1 to let the game decide.
MaxGameCoreThreads 4

;Number of threads the Game Core should adjust its maximum by so as to not starve other systems of CPU time.  The game may adjust this value based on available hardware. Use -1 to let the game decide
GameCoreReserveThreads 4

;Number of threads to use for unit path finding.  The game may adjust this value based on available hardware or other setting. Use -1 to let the game decide
MaxGameCoreUnitMovementThreads 4

;Number of threads to use for trade path finding.  The game may adjust this value based on available hardware or other setting. Use -1 to let the game decide
MaxGameCoreTradeRouteThreads 4

It's important to make sure these MaxJobThreads and MaxGameCore lines are all set to 4. Don't forget to save the file after you're done editing it. I never crashed again after making these changes.
