`multipass find --force-update -vvvv` sometimes crashes the daemon

**Describe the bug**
`multipass find --force-update` sometimes fails when running with trace verbosity. Happening on multiple OS's

**Logs**
```
% multipass find --force-update -vvvv
[2024-07-11T13:54:28.979] [debug] [async task] fetch manifest from the internet
[2024-07-11T13:54:29.449] [trace] [url downloader] Found https://cdimage.ubuntu.com/ubuntu-core/appliances/streams/v1/index.json in cache: false
find failed: cannot connect to the multipass socket
% multipass ls
list failed: cannot connect to the multipass socket
```

Reproduce the failure with `multipass find --force-update -vvvv` and compare the trace output with the daemon and socket state shown in the report. Use the failing command and follow-up `multipass ls` as the checks; done means the daemon remains reachable and both commands complete successfully.
