Hello, I am commenting from Japan using a translation site.
Sorry if my language is not correct.

I purchased this game and started it up. The first startup was successful, but then I changed the graphics settings and it crashed and has been crashing ever since.

Specifically, after listening to the anti-aliasing jokes from the graphics settings, I changed the setting to “disable fullscreen and enable only windowed fullscreen” since both fullscreen and windowed fullscreen items are enabled by default.

Then I changed it back to “enable fullscreen and window fullscreen at the same time again” and it crashed.

Since then, integrity checks, reinstallation, and deletion of AppData files have not corrected the problem.

Below is the information from the “error.log”.
