BUG: Grub says "you need to load the kernel first" after update & 1st reboot on MacBook Air 2013 Intel

[lbtbs]

Rhino Linux Version:
I don't know how to find my Rhino version, but it should be the recent version, because I updated it and since then I can no longer boot Rhino. When I select the boot option "Advanced option for Ubuntu" then there are generic and recovery mode of Linux 6.5.5-060505, but they also failed showing the same error which I mention below.

Platform:
MacBook Air 2013 Intel
