This also happens with the canary image and is happening with the Mantic daily image.
When installing with LVM and encryption, after the "remove installation medium and press enter to reboot", the user is greeted with a permanent black screen. After pressing arrow keys, the gui prompt is then shown to prompt the user to put in the encryption passphrase.
It is also somehow possible to not get the black screen by changing the grub prior to installing by removing splash from the grub options. The user is then greeted with a text-only passphrase prompt after rebooting.
