There are two different versions of the Visual C++ that cover the 2015 date range. From what I have seen from the Korean and Japanese system requirements for the 64 bit client, they both make reference to the Visual C++ Redistributable for Visual Studio 2015, and not the latest 2015 ~ 2019 Visual C++ Redistributable.
If you are having issues crashing at the Splash Screen, and have already gone through previous debug steps such as Steam validation etc, please check your version of Visual C is the 2015 only version.

"But I tried to install the Visual C++ Redistributable for 2015 and it says that 'the installation cannot be completed as there is a new version of this software already installed on this machine' ".
That's okay. To replace the 2015 ~ 2019 with the 2015 version, you will need to go:
- Start -> Settings -> Apps & Features
- Search for "Visual" and it will filter all the Visual C packages you have installed
- Go to "Visual C++ Redistributable 2015 ~ 2019" and uninstall that one.
- Once finished, run the Visual C++ Redistributable for 2015 installer.
You should be done.
