I run Mythruna as admin and normally but it only makes it to Select Display Settings and once i click ok nothing open after that
Sorry you are having problems.
Does it just exit or does an error pop up? Can you see if it wrote an error-####.log (where #### is a unique number) or a client.log file?
Do you know what kind of graphics card your computer has?
Most common cause of this issue is a graphics card that is not good enough to run the game or graphics card drivers that are not up to date.
