Boot-repair hangs (says this may take several minutes, but is still running over an hour later) when used with NVME disks

Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will reinstall the grub-efi of
nvme0n1p7,
using the following options: nvme0n1p6/boot nvme0n1p1/boot/efi
Additional repair will be performed: unhide-bootmenu-10s use-standard-efi-file

gui-actions.sh appears to not handle NVME disks and their unique disk naming properly.

I have this problem and See it documented by other users, unresolved here: https://askubuntu.com/questions/1428127/boot-repair-fails-due-to-bad-substitution-in-gui-actions-sh
a 'work-around' seems to have been provided here, but boot-repair was not used and is still not functioning as a result: https://ubuntuforums.org/showthread.php?t=2475984
