Crashes on launch after installing September patch
I played the game yesterday without any trouble. Today I downloaded the patch and launched it and I got a spinning cursor for a long time, then the screen briefly turned black, then an "Oh no it crashed" pop up from uplay. I verified the files and it still crashed. I updated my graphics drivers, uninstalled and redownloaded the game, restarted the computer, quit all other running apps, still crashed. I clicked the send crash report button, but the error message didn't have any more information about the cause of the crash.
My computer is
Windows 10 version 1903
Intel 9600k
Geforce GTX 1070 driver version 436.15
16 GB ram
