D5 Renderer crash after forced shutdown | autosave + history files won't open

Hi everyone,

I’m running into a critical issue and would really appreciate any help.

Today my PC shut down unexpectedly while a D5 scene was still open. Since then, I’ve been unable to open the file. Neither the original, the autosave, nor any history versions. D5 crashes every time, right after 5% of the loading screen.

Here’s the repeating log error:

Fatal error!
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000054

This puts me in a very difficult position professionally. Only because I had created a manual backup yesterday can I recover part of the work. But everything from today is lost, and seems completely unrecoverable.

Even more problematic: the renderings were already finished. If the client now requests revisions, I would have to rebuild the entire scene down to the millimeter, which is obviously not ideal and barely feasible.

To clarify:
– The file is stored locally (not on any cloud service)
– Autosave was active
– No folders or file paths have been altered
– Only this scene is affected others open fine

Is there any way to repair a corrupted D5 file, or to extract geometry, assets or data from it manually?

Any help or experience would be highly appreciated. Thanks in advance!

Hi @studio.lk

I apologize for the inconvenience. I want to confirm a few things:

  • Is this the same file that you were talking about on your other forum topic?
  • The repeating log error that you have mentioned is this evident every time you open D5 Render? Please clarify if the error prompt is related to D5 since it’s my first time encountering such an error prompt.

Please generate a log file for us, too, and if this is a different file, share it with us also.

Let me know if you have sent it already.
