"An Unknown Error Occurred While Accessing file"

[mackenzieRD98L]

While working on my project, my computer decided to crash - not sure why, I wasn't at my desk at the time.

Now when I open the file, it comes up with this error;

Any idea why? I have tried to transfer the file to another location (not in google drive) and it still has the same problem.

Is there a way to fix this? or do I have to use my last autosave. (Unfortunately lost about 2hours of work)

Have you tried using the Audit option when opening the file?

[mackenzieRD98L]

Yes I have. Did nothing. still displayed the same result

[hmunsell]

if it's a workshare enabled file (uses worksets), pick Audit and Detach from Central. This will effectively create a new central model.

If it opens, you can save it over the original or save it to a new name.

In addition to what @hmunsell mentions, you can try opening the file with worksets closed (i.e. not "Opened") and narrow down the possible problem to one specific work set by opening them one at a time.
