[2020] Crusader Kings 3 crashes upon launch

Lots of DirectX 11 errors in that log, and I see you are on Windows 8.1 . Strangely my first suggestion is to update that Intel video driver from 2013, even though the game is not running on it. Start with the Acer support site, if no good then Intel themselves:

Drivers & Software

Download new and previously released drivers including support software, bios, utilities, firmware and patches for Intel products. downloadcenter.intel.com
If however you were contemplating going to Windows 10, now might be a great time to make the leap!
