Unfortunately, these bits can't currently be installed via the CLI You should be able to install the public previews of VS and use those bits.

@PureWeen @jsuarezruiz The issue will only be reproduced when using the command to install maui. VS already includes maui for 6.0.x, so I don't think it has anything to do with VS. Maybe this issue will not reproduce after 6.0 SDK GA. I will continue to track this issue.
