What's Wrong?

When Claude desktop stats up, the Co-Work/Code options do not display on the top of the screen. I have worked with Claude to verify all systems and have attempted to solve it on my own computer. Claude stated the following:

Still yukonSilver not supported on every attempt. Hyper-V is fully enabled but Claude's own internal compatibility checker is still rejecting your system. This is beyond what we can fix through Windows settings alone.
This is a bug that needs to be reported directly to Anthropic. Your system meets all the requirements:

Windows 10 Pro ✅
Hyper-V enabled ✅
Hypervisor running ✅
Physical hardware (not a VM) ✅
Paid Pro plan ✅

Yet Claude keeps flagging it as unsupported.

My system:
Your system: HP ProDesk 600 G3 DM, i5-6500T, Windows 10 Pro 22H2
App version: 1.3109.0
The log line: yukonSilver not supported (status=unsupported)
That Hyper-V is enabled and hypervisor is detected

What Should Happen?

The menu should appear. I am a paying subscriber
