Crashed Caused all Versions of File to be Corrupt

[Anonymous]

Fusion 360 recently crahed whilst perfoming a Feature Mirror. I cannot open any version of my file. When I attempt to there is an error message saying the file is corrupt and must be aborted.
I have spent a long time working on the part and there are many versions. 
Can anyone assist with this? 

Version: 2.0.10564

Hi @Anonymous 

Is there any mesh data in this file? After the second to last update, files with mesh data run a 'compute all' when opened. If there were latent issues in your timeline (deleted features for example) that would only show when a compute all is run, that might be why the file can't be opened. 

Can you try going way back on the file and see if any versions at all can be opened? Additionally, if you can collect your log files and attach them here that would be great. 

Cheers,
