I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms

When the game is started, shortly after the splash window appears, two error dialog boxes also appear (see below for a screenshot depicting these dialog boxes). When the two error dialog boxes are closed out, after a brief pause, the splash window disappears. The program produces no further observable behavior, but it remains running as a process and must be killed (such as by clicking the "Stop" button within the Steam client's UI).

Reproduction

The above behavior occurs consistently when running the game using Proton version 7.0-2 (as well as other Proton versions that I've tried, including Proton Experimental as of the time of this report; the latest third party fork GE-Proton7-17 also produces this behavior, too). This game's ProtonDB entry suggests that nobody else has managed to get this game working in Proton yet, either.

Start with the attached steam-1020780.log and screenshot, then reproduce DarkStory Online (Steam AppID 1020780) with Proton 7.0-2 and the other listed Proton versions. Done means the startup failure is explained and a verified compatibility fix or clearly documented blocker is identified.
