Qubes 4.2-rc5 update did not generate the initramfs images in the system partition /EFI/qubes. Broken installation, I can’t boot anymore

Here are the partitions on the Qubes drive. P1 is the system partition. Lsblk indicates that p2 is a crypt swap partition. I can’t mount p2 to see what is inside. Logically , this should be a boot partition, but I don’t know how to mount it and see. P3 is encrypted and can be mounted with correct password: it includes dom0 and virtual machine images

fdisk -l /dev/nvme0n1

Device                      Size	 Type
/dev/nvme0n1p1      600M	 EFI System
/dev/nvme0n1p2      1G 		 Linux     filesystem
/dev/nvme0n1p3      429.9G 	 Linux filesystem

lsblk  /dev/nvme0n1p2

NAME          	  RM SIZE RO TYPE      MOUNTPOINTS
 nvme0n1p2         0   1G  0 part

I have copied the grub.cfg in my previous reply (there is also grub.cfg.swaprpm). The UUID mentioned there does not match any UIUD returned by blkid command.

I don’t see any image file in unencrypted partitions.
