How do I fix my game

When I try opening my game it shows this message and I have no idea what to do to fix it.

Press F12 and check if there's any error messages in the console.

I hope you have a backup in case it got corrupted.

You can also try opening it in an older version like editor.construct.net/r496 which is just one version earlier.

Thanks but there are no errors and it does not work on older versions. Is there another way? thanks

I’d also try opening a previous version from Google Drive if the project was stored there. The version history can sometimes recover the file from before the corruption without losing the newer work.

I don't know how to manually recover the project and I regrettably did not make back ups or use google drive. I tried Emailing support 5 times but they never replied.
