VM Name: QemuEmulatedDebian.UTM
Used within UTM.app all the time.
VM Backup Name: QemuEmulatedDebianBackup.UTM

When something goes wrong with the QemuEmulatedDebian.UTM, quit UTM.app.
Delete QemuEmulatedDebian.UTM
Duplicate QemuEmulatedDebianBackup.UTM as QemuEmulatedDebian.UTM
Open UTM.app
Start QemuEmulatedDebian.UTM

Thanks @osy. This one bit me too. Wish I'd searched the issue tracker before spending an hour trying to figure this out.
Note that as of this writing, the version in the Mac App Store is 4.4.4, which doesn't include this change.
Also note: although the error message would imply that it was something related to filesystem permissions, fiddling with the "Full Disk Access" security settings in System Settings doesn't do anything for this issue.
@osy, I was able to work around it using the advice from this discussion, but I'll keep an eye out and if it's something reproducible, I'll collect more information for a proper bug report. Thanks!
Enabling FDA is just something I do out of pure naïveté on macOS when I see permissions-related errors. I'm not proud of it, but that's just the level I'm at sometimes.
