As said before it worked some weeks ago and still works on a 20.04.5 live usb. So there is something broken in the 21.04 setup of the whole grub/kernel/efi stuff.

I stumbled about the releasenotes from 21.04 now talking about some shim issue. and i found https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1925010 and https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1925064.

I have the error "efi: Failed to lookup EFI memory descriptor for 0x00000000d75f2000" in the logs like which seems to releate here:
