B4J Question Does not open the project, Damaged project?

[Juan Carlos Bastidas]

Good afternoon guys.
I turn to you because I don't know what else to do.
I am doing a project in B4J my machine turned off and when I turned it on again I cannot open the project
I get this error, I looked for it in the forum but I can't find it

I can't upload the project here because of the weight, but I uploaded it to the hosting and it can be downloaded from this link

Check the .b4j file. It is probably corrupted.

Fetch the latest copy from the AutoBackup folder.
