chiggeuk That means that at least one of your saves is corrupt, but whether that's fixable or not is unclear. Please make sure you have a new save available in-game, and move your old saves back to the saves folder. If you get a notification about duplicate files, skip that file and rename it so it doesn't share a number with any other save. The number in the save name needs to be eight digits long and contain only the digits 0 to 9 and a to f.
If the game crashes again before you get to the Main Menu, try adding back the mods and custom content you were previously using with your old saves, updated versions where necessary.
By the way, there's a master bug report for this issue, and EA_Cade has asked for saves here:

It looks like custom tattoos may be the culprit at least some of the time.
