Unable to start Agents with Shared Compute

[WaterBoiledPizza]

Describe the bug
Unable to start Agents with Shared Compute. When I press start, it will start loading forever.
I don't think it is not doing anything as I observed increased request of the shared compute when i try to start it up.

The agent settings shows the following message that I'm not sure what it is about, nor can I search any documents about it:
Buzz is waiting for the relay's member roster. Try again shortly; if this persists, check the relay's membership configuration.

Steps to reproduce

1. Follow up on Unable to start share compute due to missing library libhipblas.so.3 #5552
2. Find the Fizz card on the Agents screen.
3. Click the small play badge over its avatar

Expected behavior
Fizz will then start running and respond to messages

Version and platform
Find your version at the bottom of the Settings sidebar. Write "unknown" if you can't determine it.

• Buzz version: v0.5.9
• OS: Ubuntu 26.04 LTS
