Apologies for my initial post that was lacking the necessary context and credentials.
We're currently investigating the issue of the game splash screen getting stuck, not allowing entering the game. To get more information about what exactly is happening when the problem occurs, we'd greatly appreciate if anyone experiencing the issue could create and send us a Process Monitor log of launching the game from Steam. This should allow us to pinpoint the cause of the error and deliver an update fix immediately. To send the Process Monitor log, you can upload it to https://uploadfiles.io and then send me a link to the download via a Private Message.
Additionally, as a quick test, could you try starting the game from Steam, and then within ~20-30 seconds terminate the game process (SummerCamp.exe) in Task Manager. Do you get any error message pop-up after this?
Please feel free to contact me directly via Private Message and we can troubleshoot it quickly further that way as well.
