Recover data after failed OS update? img file

So last night I updated to the latest 8.0 rc3 (from rc1) however something must’ve got corrupted and it will no longer boot (HA OS in VMware on a Windows host machine, so it’s a vmdk file)

ALL past updates I’ve had no issues with until this one. shame on me but I didn’t have a good backup, I’m trying to recover at last my dashboard yaml file as I had a lot of custom code done in there.

So far the closest I’ve gotten is using 7-Zip to extract the contents of the VMDK, which then lists out 8 separate “.img” files. I can then proceed to extract img files EXCEPT, of course, the data file which I think is what I need. 7-zip just says it can’t open it as an archive.

Anyone have any tips to try that I can get access to the contents of this data img file?
