Unhandled Exception in the vSphere 6.5 UI after adding raw device to VM

[helgew]

After adding a raw device (based on an SSD disk) as an "existing hard drive" to a VM, I am getting an Unhandled Exception whenever I am trying to edit the VM's setting:

Hitting escape a couple of times, the UI seems to be unhappy with the size and the number of shares specified for the disk. Those fields, while grayed out, are highlighted with a red frame. I am not able to use the UI to make any changes to the settings.

I have added raw devices to other VMs without problems (haven't tried with this vmdk though) and the affected VM is able to use the disk just fine.

Any advice or pointers would be greatly appreciated!

Create a VMFS file system on the SSD and use a vmdk for Mac OS or attach the Lun as physical RDM.

Well this happened in client as well and you can simply remove raw device from VM, shut down VM remove from inventory.  log out, log in client, add VM back to inventory and add raw device again. it's probably a bad DB pointer for the object.

It happens.
