No display at all after starting to boot machine

if the next kernel upgrade doesnt fix this and i chose to go ahead with the upgrade, my qubes will no longer be accessible (the last 3 kernels are only available in the grub menu)

Not booting with Linux 6.6.48 but still booting with 6.6.42

You won’t be locked out, the current kernel (6.6.42 in your case) that Qubes OS is using when you update dom0 won’t be removed during update.
