Correct, you can run x86 Windows/Linux/macOS on a x68 Mac, or ARM Windows/Linux/macOS on an ARM Mac. You can’t run Windows x86 with Parallels on an ARM Mac.
Because Windows 11 ARM provides emulation to run x86 code on it. Your Ubuntu ARM does not provide emulation. If you follow the link I posted there is information on how to install emulation if you want to run Linux x86 code on a Linux ARM installation (the link to askubuntu about the ‘translation layer’)
The options you have:
- install UTM on your ARM Mac and use a Linux x86 guest
- try to install a ‘translation layer’ for your Ubuntu ARM so it can run x86 code
- wait for a future Xojo version to build Linux ARM
