macos m1 ubuntu guest "bad access"

**Describe the issue**
I do not get a hit matching my issue when searching this project for "bad access". I get intermittent UTM failures running Ubuntu VM guest(s) with UTM on mac mini m1. The timing is unpredictable. But it usually happens within a week, sometimes more than one failure in a day. Happens when running a single guest or multiple guests. Very rarely happens when actually using the guest, usually just crashes when using other apps.

All Ubuntu guests are os release:

**Debug log**
There is substantial private / confidential information involved in the Ubuntu guest VMs. Sharing the
debug log would seem like a breach of contract or trust. I do not currently enable the debug log. You can delete my issue if the debug log is required.
