Solution for game going black screen on launch with the error message file corrupted.

[High BMI KEL]

I've encountered this problem after installing the Frontline 59 DLC,

Game booting --> black screen --> two corrupted file message pops up --> game auto close

Found a fix for it (it worked for me at least). So I'll just leave this here to those that also encountered the same issue.

1. Go to local files, locate a folder named ProjectWingman and 2 files named Manifest_DebugFiles_Win64 and Manifest_NonUFSFiles_Win64.
2. Delete these files.
3. Verify game files integrity on steam after deleting the files.

The game launched without any problem after doing that, so it might be worth a try for those that encountered the same problem.
