Clair Obscur: Expedition 33 marks the exciting debut of Sandfall Interactive, now available on PC and consoles. Powered by Unreal Engine 5, the game delivers stunning visuals; however, players may experience some performance issues. Fortunately, there are various settings available that can be tweaked to optimize your gaming experience.

If you’re encountering crashes while launching Clair Obscur: Expedition 33, either immediately or following the benchmark message, don’t worry—this guide outlines effective solutions for resolving these issues on PC.

Resolving the Clair Obscur Expedition 33 Launch Crash

Many Steam users have reported crashes occurring right at the game’s launch or right after the benchmark display. While such issues are often linked to corrupted files or missing redistributables, recent findings suggest that the problem may actually stem from the Steam Overlay settings.

Although the precise reasons for this remain unclear, it appears there may be a check within the game that necessitates the Overlay’s activation. Here’s how to enable it:

Open the Steam client and click on Steam in the upper left corner.
Select Settings and navigate to the In-Game tab.
Ensure that the first option is toggled on to enable the Steam Overlay globally.
