[BUG] failed to add Plan9 share 'e': HRESULT 0x80070070 on Windows 11 Pro 26200.8117

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

I am unable to work in claude desktop cowork since the previous version of claude desktop.

Version: Claude 1.1062.0.0
OS: Windows 11 Pro Build 26200.8117
Error: failed to add Plan9 share 'e': HcsWaitForOperationResult failed with HRESULT 0x80070070
Reproducible: 100%, after a complete bundle delete and redownload
Steps: VM boot succeeds, crashes at add_plan9_shares step
I have an open support ticket 215473772927962 - I am supposed to be contacted by a support engineer, 4 days later nothing happened. As a paying pro plan user, this is somewhat frustrating.

What Should Happen?

Claude should allow to work in cowork and cowork projects. Scheduled tasks should work.
