Hi.
There is no way you can turn the export version into the original project.
You can only get the graphics and sound.
If the data on your laptop is erased, it does not mean that it is gone, the main thing is not to write anything on top. All deleted data from the hard drive can be recovered after deletion, if you do not know how to do it.Contact a professional.
All people are divided into two types, those who make a backup and those who do not make a backup yet.
Sorry bro, but it happens.
