Guys, I really don't know what is going on for you. But let's try this again step-by-step.
1. Download Win64 version from OP (Yes, the 64bit (RL5 PE P1), because the Win32 is the old unpatched version with a bug).
1.1. Check Game_Data/Language folder for missing English.zip (Note: English.zip needs to be there.)
2. Uninstall Visual C++ 2019/2017/2015.
3. Install Visual C++ 2015 x64 (because we downloaded 64bit version of the game)

4. Restart your computer.
5. Start the game.
6. Check if English flag is visible on main menu.
7. Start a new game.
8. Black/White screen remains -> please upload your player.log file as text file (.txt) here.
Player.log file is stored in your user's
hidden AppData/LocalLow/VNGINE folder.
Visual C++ 2015 is explicit needed, because Unity doesn't support the new webp image format natively.
