Hi all, does anyone have encountered this error message before?
I couldn't open my project file, and this error message pop out.
Why does this error occur?

It is possible that project is fully corrupted and not able to recover automatically. You can try to use the manual recovery step as mentioned in:

Hey, are there any solutions besides restoring the corrupted project? How can we prevent it in the future? 

[Aniket]

To prevent it, you can use a local drive for saving projects and keep the temp directory on the same drive as well. In addition to this, you may want to exclude the said local directory from programs like antivirus, backup etc.
