Construct 3 crashes and breaks the project

I worked on the project for 8 hours, after which construct 3 crashed, and after the launch of the project, I saw that all my accumulated mechanics stopped working. My code is clean, I did not make any changes to the character mechanics, but they broke and do not work. What should I do ? I've been working on the project for months and now it's broken...

Recover from a backup save.

Make regular backup saves. Make new saves instances on a regular basis.

When Construct crashes, you generally have a dialog with some code to provide when doing your bug report, and you can save your project using the dedicated "Save projects" button as well.

In those case, save a new instance of your project.

And do fill a proper bug report to help our dev team prevent further crashes.

Consider sending a message with a copy of your project (.c3p file) to supportkxf@construct.net in case we can salvage it.
