luks – repair boot with encrypted partitions

I am trying to repair my system boot with boot-repair.
I used to have a dual boot with Windows and Ubuntu and installed Manjaro alongside.
Unfortunately, Windows does no longer show in the boot menu.
I posted my boot info in this paste.
When I installed Manjaro, I created two encrypted partitions. Boot-repair has the following warnings:

• LegacyWindows detected. You may want to retry after deactivating the separate /boot/efi partition
• You may want to retry after mounting your encrypted partitions

I don’t understand if and how I should deactivate the separate /boot/efi partition and how to handle the encrypted partitions.

I mounted my encrypted Manjaro partition, i.e. sudo cryptsetup luksOpen /dev/nvme0n1p10 manjaro and then sudo mount /dev/mapper/manjaro /mnt/manjaro

Any help is appreciated.
