What I do is:
I start the same as in that web page, except that as I don't use btrfs it is far easier. When I get to the section in "Change root and install grub", do that chroot, then:
Just booted the rescue system and noticed a hint before the login prompt to use the tool mount-rootfs-and-do-chroot That one with the root fs as parameter prepares almost everything and chroots directly. Another mount -a later I was ready to work in the installed system.
Second step
start yast in _text_ mode (call "yast" in xterm, konsole, etc). Go to "System"/"Boot Loader"
Check that all things look correct, then on tab "Bootloader Options" change the timeout one second up or down. The side effect of this tiny change is that all files are written to destination on accept.
did this - changed a tiny thing - and saved. And finally: My bootloader is back! Thanks to everyone for the pointers. So I would expect that this happens for everyone else running Windows 11 that it wipes the opensuse boot stuff when doing some sort of update once in a while? I'm wondering why I haven't found multiple references to such a problem? Wolfgang
