Hello Bertyfredo,
Which OS are you using? If it is Windows, please check for the error signature in the Windows Event Viewer -> Windows Logs -> Application section related to metashape.exe or any other processes related to the hard crash time. And can you please also share the processing log of Metashape from the project processing start up to the crash? (logging should be redirectred to the file via General Preferences tab in advance).
Also please specify the driver version installed. As far as I am aware, NVIDIA driver 460.79 can be considered unstable, according to the massive user reports on NVIDIA forums, so I can suggest to roll back to the previous driver version.
