Installation • Asking passphrase twice for LUKS after installing KDE Plasma

Hi

I have a LUKS encrypted drive containing the root system excluding /boot and /boot/efi.

$ lsblk...|-nvme0n1p5   259:5    0   512M  0 part  /boot/efi|-nvme0n1p6   259:6    0   200M  0 part  /boot`-nvme0n1p7   259:7    0 351.2G  0 part    `-cryptroot 254:0    0 351.2G  0 crypt /home/.snapshots                                         /var                                         /usr/local                                         /tmp                                         /root                                         /home                                         /opt                                         /.snapshots                                         /

Right after booting into Debian 12 for the first time it asks for the passphrase like it should do after the GRUB menu and initramfs has loaded. But after installing a DE, KDE Plasma, it first asks for a passphrase before the GRUB menu shows up and then after initramfs has loaded. The first time it asks it doesn't matter what I type there, correct or the wrong passphrase, it will proceed to the GRUB menu.

My boot partition is not encrypted. There is only 1 entry in /etc/crypttab. Is there something wrong in the GRUB config? In it I have set GRUB_ENABLE_CRYPTODISK=y and GRUB_CMDLINE_LINUX_DEFAULT="quiet,rd.luks.uuid=<uuid of it>". But by my understanding not having those lines in the GRUB config it shouldn't know the drive is encrypted since crypttab is on the encrypted drive.
