Maybe you have the same problem I did? Did you try my fix?
If that fails, try removing half of the files from "DocumentsDeadIslandoutDataMenuScr" and seeing if you can start the game.
If it fails swap the files you removed with the files you left in the folder.
If that works but half of the files removed back in and see if it works.
Keep repeating this process until you find which file is causing the crash (for me it was 'MenuUpgradeCharacter.xui', but it may not be the same file for all we know)
If it works with all but one file then experiment with different screen resolution values on the lines I have highlighted
5040.000000
1050.000000
MenuUpgradeCharacter
5040.000000
1050.000000
true
MenuUpgradeCharacter
MenuUpgradeCharacter
I_Image_2
888.000000
622.000000
88.319992,45.000000,0.000000
until the game stops crashing for you.
