Description

I've checked the Issues, haven't found anything similar.

**Describe the issue**
When I opened a VM that worked on a previous macOS version (15.5), it didn't boot successfully and showed error messages like this:
"QEMU error: QEMU exited from an error: gemu-aarch64-softmmu:
-netdev vmnet-shared,id=net1:
cannot create vmnet interface:
general failure (possibly not
enough privileges)" and then it said "Internal error trying to connect to SPICE server."
When I removed the bridged network interface and restarted the VM it worked fine, and there remained an interface connected through "Shared Network" and the internet connection inside the VM was available

**Configuration**
* UTM Version: 4.6.5
* macOS Version: macOS 26
* Mac Chip (Intel, M1, ...): M1 Pro

**Crash log**
The UTM app itself didn't seem to crash.

**Debug log**

**Upload VM**
The problem seems to happen whatever the guest OS is and whatever architecture it runs on, so I don't think it's related to a specific VM.
