How does the file verification error occur?

Corrupted game files, outdated graphics drivers, outdated Windows version, incompatible mods, launcher issues, and disk drive failure are common causes for this error.

How do the game files get corrupted?

If the game was not installed properly, i.e., over numerous gaps, or if an update was interrupted, the game files can become corrupted. That’s why verification of game files is important.

Why does skipping Larian Launcher solve the issue?

The Larian Launcher is far from perfect and has been known to cause issues like most third-party launchers available for games on Steam. Therefore, skipping it altogether can alleviate many issues and reduce start-up time.
