grub efi luks encryption, how avoid "decrypt master key"

mo flag

because I accidentally deleted the luks key slot saved in the keyfile the system (lubuntu 22.04, grub efi) started as normal with password to decrypt master key, which takes very long because of grub being slow. But then the luks partition can't be found and grub hangs.

If I delete the keyfile, the system asks for the password twice, once for decryption of master key then for the luks partition.

If I set GRUB_ENABLE_CRYPTODISK=n' in the file '/etc/default/grub' and run update-grub and grub install the system boots without asking the "decrypt master key" password. But now again the luks partition is not found and the system hangs again. I would like to just have to type the password once for the luks partition.

Any ideas how this could be done? Thanks in advance.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
