Windows bootloader is not in the list of boot options. Which is rather unusual (especially after Windows update that apparently updated the bootloader).

Educated guess - it has always been this way, you just did not notice it. The NVMe boot entry most likely loads \EFI\Boot\bootx64.efi which was overwritten by Windows update. Prove output of
ls -lR /boot/efi
(after mounting it in live linux).
Your openSUSE bootloader was removed
./EFI/opensuse: total 0
So you need to reinstall it.
Tried it pretty much like described here: https://en.opensuse.org/SDB:BTRFS#How_to_manually_re-install_grub_on_opensus... But not only ran update-bootloader but also ran yast2 bootloader where settings looked about right and confirmed it. Now there is EFI/opensuse/grub/grubx64.efi (only that) But I still cannot boot from there. What else to do in addition to "reinstall the bootloader"? Thanks, Wolfgang
