Hello @novel fog Could you also share your save file and crash log here later?
To find the save file, you can copy-paste this file path to the File Explorer: %localappdata%\ProjectCoral\Saved\SaveGames

As for the crash log, it's located inside the Crashes folder located in the Saved folder (the XML file). Thank you so much.

here you go! the saved file is from 2022, so i'd be starting a new game and deleting that one anyway. i dont plan on using that saved game.

We're really sorry about the crash you experienced! We’ve checked with the team, and they’re aware of the issue and are currently working on a fix.

Thank you so much for your patience while we work to get it sorted out.

Hi @novel fog. I'm also part of the team. Thank you for sticking with us and for your support while we work on the crash issue you’re experiencing in Coral Island

After digging into it a bit more, it looks like a third-party app might be clashing with Unreal Engine’s online system and stopping it from loading properly, which could be causing the crash. To help us check if something else is using the same network port, could you try these steps?

• Launch Coral Island (even if it crashes, just leave the Unreal Engine crash window open).
• Open Command Prompt (type cmd in the Windows search bar and hit Enter).
• Type this command and press Enter: netstat -ano | findstr :27015
• Take a screenshot of the result and send it here.
• Then, open Task Manager (right-click your taskbar).
• Right-click on the column headers in Task Manager and turn on the PID (Process ID) column.
• Take a screenshot of that view too and send it over.
