I did not look there as the document you linked says the following:
"-Reinstall VCRedist and DXSetup
In the following location:
C:\Program Files (x86)\Steam\SteamApps\common\Ashes of the Singularity Escalation\_CommonRedist\vcredist\2017
Run: vcredist_x64.exe ('Repair' option when prompted)
In the following location:
C:\Program Files (x86)\Steam\SteamApps\common\Ashes of the Singularity Escalation\_CommonRedist\DirectX\Jun2010
Run: DXSetup.exe
Reboot and try to run the game again."
I have reinstalled the game and ran vcredist_x64.exe 'Repair' option and DXSetup.exe. I have now been able to play the game for almost an hour with no issues. Thank you.
