Describe the issue
I have an existing VM that I haven't touched since at least 2.0.20. When I try to start it or edit its QEMU arguments, UTM crashes with a NSInternalInconsistencyException caused in UTMQemuSystem.m line 472.

472  [self pushArgv:@"-device"];
473  [self pushArgv:self.configuration.displayCard];

Configuration (required)

• UTM Version: latest
• OS Version: latest
• Device Model: iPad Pro 11" A12X
• Is it jailbroken (name jailbreak used)? No
• How did you install UTM? Xcode
