TL;DR

The issue is likely related to a problem with adding a Plan9 share, and a potential workaround could be to check the system's disk space or permissions.

Guidance

• Check the system's disk space to ensure it's not full, as the error code 0x80070070 can indicate a disk space issue.
• Verify that the user has the necessary permissions to add the Plan9 share.
• Review the logs to see if there are any other error messages that could indicate the root cause of the issue.
• Consider reaching out to the support team again, as they may be able to provide additional guidance or assistance.

Example

No code example is provided, as the issue seems to be related to a system or configuration problem rather than a code issue.

Notes

The error message HcsWaitForOperationResult failed with HRESULT 0x80070070 suggests a system-related issue, and the fact that the problem started after a version update implies that it could be a regression bug.

Recommendation

Apply a workaround, such as checking disk space and permissions, to try to resolve the issue. If the problem persists, it may be necessary to wait for a fix from the development team or to roll back to a previous version of the software.
