Not opening on Mac.

It looks like the game is having trouble connecting to Steam. Try restarting Steam and make sure you are running the latest Steam client by checking Help -> About Steam. Mine says it was built June 8, 2021 at 15:26:38. Are you using the Steam Beta Client by any chance?

Just tried, nothing different. Using normal steam, fully updated. 

 

I had the -force-glcore fix from before for a graphic issue in the general tab in the steam property options. Removing that allows the game to open, but the missing graphics aside from bubbles, text and overlay starts again (mostly black).

returning the -force-glcore text in general returns to the game just not opening.

 

Edit- I can force the game to initialise and open to the Klein screen. Just before the game window closes/crashes, the following screen (image attached) pops up for less than a second before close. The red text on the left says "Steam not initialised in time"

new information/update.

That's an interesting discovery. Could you post your Player.log file with -force-glcore removed and another after you re-enable it again?

Glcore removed log and known graphic/texture bug log and screenshot

When attempted to launch via steam with -force-glcore replaced. no window opening.

here's the steam info just to confirm your first reply.

Thanks, we identified the issue and are working on a fix.
