How do I Fix this error? Did I just Lose Everything?

I am a new game maker, and I didn't have backups on because I am using a small computer without a lot of storage. I Have been saving my project, but not as separate files. I think this costly mistake may have cost me months worth of work, but I am reaching out here as a last hope.

Here are the errors my console is reading. I was working on my game and suddenly the ground textures all disappeared, and the background turned pink.

Is there any way to recover this?

Send your project to ashleyahi@scirra.com and I'll see if it can be recovered. However it's worth emphasizing you should keep regular backups for any important digital work with any software. Otherwise something like a hardware failure risks you losing all your work permanently.

Ashley I sent the project over to that email. Thank you for taking the time. In the meantime, I will start removing things from the project, I am assuming I can just delete them from the project menu within the editor until I find the issue.

Thank you both.

I managed to recover the project and sent it back to you - there was a corrupt PNG file in the project. I'm looking in to improving Construct's error logging to identify the corrupt file to make it easier to find if it happens again.
