Do You mean the screenshot with UEFI shell? You usually do drop to UEFI shell when firmware did decide it can not start your efi application. Other option is, we got failure and did exit loader.efi.

it may help if you attempt to start loader.efi manually from ESP, by entering: FS0:/efi/boot/bootx64.efi  — there may appear some messages...
