VMWare Workstation 16.2.3 Power failure, VM will not boot, VMDK error, grain

Hi, I'm running VMWare Workstation 16.2.3 and I experienced a power loss while running 2 Windows 7 VMs.

One VM came back up normally, with just a 'windows did not shut down properly' type of message.

The other VM will not power on and VMWare complains that the (single) VMDK file is corrupted.

Running vmware-vdiskmanager -R on the single VMDK file (max size 60GB, current size=21GB, no snapshots, grow as needed) for the VM that will not power on,  gives the following error message:

[ The virtual disk, 'F:RV_sd-0.vmdk', is corrupted and cannot be repaired. ]

I've attached the section of the vmware log file where it complains that various grains are referenced by multiple Grain Table Entries (GTEs). There are a lot of them, 5240 lines, in the format

Grain #nnnnnn [at]YYYYYY is pointed to by multiple GTEs

There wasn't much activity in the VM when this happened, so I'm not sure why the thousands of badly referenced grains.

I'd like to recover the handful of MS Office documents that were saved on that VMDK after my last backup of the VMDK.

I've also tried SolarWinds converter and VirtualBox7 virtual disk manager to see if they could open the VMDK. Both failed to open it and complained of an error.

Any suggestions?

Thanks!

I'd like to bump this discussion thread (it's been about 6 months and has quite a few views but no further comments).

Just wanting to see if anyone else has run into this issue, or if any VMWare guru can recommend a course of action.
