So, I was having the same ctd without any errors after battles after the VC update, The workaround is
1- switch back to old nvidia display driver <400 , I used 399.24 or something
2 - DO NOT use quick save or quick load, for saving in campaign or even before battles, Do not use autosaves either, Use manual saves, and you can pretty much manual save before any battle. I generally don't recommend overwriting but do it if you are out of space.
3- Use DX 11, Don't use dx 12 , Other than some rare cases, DX12 is working like hell, and making the game crash and slow down, so use dx11
4- Lower your settings just a little bit, I have a 970 and I keep it medium-high, so you don't face overheating problems
5- Verify game files via steam
6- Pray to god it works for you!
