Dead key @ in vm (linux) within Apple virtualization

**Describe the issue**
Within Apple virtualization, key @ (top left key under escape key on French MacBook Pro keyboard) is dead. Keyboard is well configured in VM (French(Macintosh)).
Tool 'xev' on ubuntu does not report any event when I hit the @ key.
No problem if VM is configured to use QEMU.

**Configuration**
* UTM Version: 4.0.9
* macOS Version: 13.0
* Mac Chip (Intel, M1, ...): M1

**Debug log**
None because VM use Apple virtualization
