i im new to fallout 3

So when I press play in the launcher the launcher closes and doesn't open the game. Does anyone know why this is happening? If so please help.

The launcher starts, but when I click on "Play" nothing happens... any clue?

Recently bought the game and can´t start a new save, the game crashes and close right after I click on New Game option. Does anyone know how to solve it?

I have read the other discussions relating to the game not starting on windows 11. I have tried the mods suggested on there and all the work around's I can find, yet it still will not work. I get past the launcher menu, then press play and it crashes before it shows anything but a black screen....
