Hello, 

We have this critical error message "Substance 3D Painted encountered an unexpected error and is now exiting, please restart Substance 3D Painted and send a crash report.

Reason: Failed to relocated to saved project file ..."

Do you know what is the problem? We have free space in disks and 128GO RAM ... 

Thank you in advance.
