Could not open file error. Also other file version affected. Help needed

[massimo.pastore1963]

I was working on a 10 hours modelling session, the file I was working on was on version 15, then, as usually, a software crash stopped Fusion to work. When I restart Fusion the file became corrupt and all my work was lost; I only can open version 11 of the file but it's an old one, without the recent modification. Any chance to get last version? (15 or 14, 13 too) . The logs seems to be ok, version 15 (that is now corrupted) was uploaded succesfully on  Cloud (20220107T213147 I 1668 Finished autosaving document: Isotta_telaio_cassonato_06012022 v15) at 21:31:47, why is now corrupted?

I use Windows 10 operating system.  The process of recovering files, that I saved to the cloud, is outlined in the Screencast.  Similar folders exist on the MAC but I cannot tell you how to get to them.  I emphasis that these are files that were saved to the cloud.  If the file had not been saved before Fusion 360 crashed, the file will not be in this folder.  This process may or may not work for you but it is worth a shot. Good Luck

Thank you for the advice John, but I've already try this step without success, also with previuos file versione (14, 13 etc) always file corrupt error...
