[GavBurke]

For context, this build used to work, I now install windows updates as part of the build and get this "invalid memory address or nil pointer dereference" error ever since.

[SwampDragons]

Can you share that repro template with me?

[GavBurke]

Apologies can probably close this, got around it now by using the Packer reboot provisioner, as this error started after installing Windows Updates and now doesn't happen with a reboot - we do have another issue but that's with Stackdriver Logging not starting on Win 2019 but not a Packer problem ;)

I'm going to lock this issue because it has been closed for 30 days ⏳. This helps our maintainers find and focus on the active issues.

If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
