There isn't a set way to fix this problem, it's happened to quite a few people now and is always solved differently from the previous time.
I suggest checking first if your pc can actually run it.
Then check if any background applications are causing potential crashes.
if not these two, try updating the game to the beta mode on steam and if you're on the beta already, go back to current version.
If again, that didn't work, uninstall everything (IF YOU WANT TO KEEP STUFF BACK IT UP OR PUT IT IN A SEPARATE FOLDER) This last part is worst case scenario but it might need done.
This is if you're on steam, if you're on standalone, I can't help.
Edit: Checked now, these can still work on standalone.
