While using beta version Unicode (UTF-8) in Windows 10 language settings, Minecraft launcher is opening, but if you try to play any version, it instantly crashes with Unknown error. This setting is required to open another computer program, but Minecraft doesn`t work with it.
This continues to happen with various java settings (tried 3 versions), reinstallation of Minecraft Launcher, rebooting computer, Win8 and WinXP Compatibility Mode and opening as administrator.
