@Gps2010 how did it change, earlier on we had the nvme device mounted as /boot/efi! Now itās sda1???
OK, so lets look at the nvme device;
umount /mnt
mount /dev/nvme0n1p1 /mnt
ls -laR /mnt
No rebooting!
@Gps2010 likewise sda and sdb are flip floppingā¦ thatās one funky motherboard!

its an Asrock is all I know 
@Gps2010 when did you install Tumbleweed? Did you select systemd-boot?
Letās see if this works; efibootmgr -c -L "opensuse-tumbleweed" -d nvme0n1p1 -l "\\EFI\\opensuse\\grubx64.efi"
Posting my $.02 here, as Iāve has similar problems with grub in multi-boot multi-drive condition . . . . One thingI learned the hard way is that if there is only one /efi/boot partition, which it looked like at one pint in the thread, there was . . . then, in my case, if I did an OSX security upgrade, OSX would wipe the UUID numbers of the linux installs and grub couldnāt find the partition.
So, separate /efi/boot partition for linux and another one for Windows.
And, something very handy is to have SuperGrub 2 cloned to usb drive to find and boot installed systems that the internal grub ācanāt find.ā Very handy.
I have no idea, about your first question.
What got me into even bigger trouble after the windows update, was me selecting something on the first page of the bootloader.
Then Tumbleweed was no longer recognized as bootable by my mobo.
localhost:/home/guus # efibootmgr -c -L "opensuse-tumbleweed" -d nvme0n1p1 -l "\\EFI\\opensuse\\grubx64.efi"
Could not prepare Boot variable: No such file or directory
Really? I see what seems to be two problems with it, one of which might account for āCould not prepare Boot variable: No such file or directoryā. These worked for me (found in my notes):
## gb250 2022-11-08
efibootmgr -c -L "opensusetw" -d /dev/nvme0n1 -l '\EFI\opensusetw\grubx64.efi'
## ab250 2019-08-18
efibootmgr -c -L "opensuse153" -l '\EFI\opensusetw\grubx64.efi'

Will this be easier to fix if we take window from the equation?
I could even for now disconnect that hard disk, then later reconnect it.
(and not use grub to boot windows but my motherboard boot menu)
( Thinking out-loud )
I will try now, was first waiting for your response.
Wanted to make sure you and mrmazda are on the same page.

@Gps2010 Iām at a lossā¦ your setup is sub-optimal with multiple ESPās (/boot/efi) and that disk changing may not be helpingā¦
See what happens on a rebootā¦
I am totally confused, but might be very happy 
Need to have a look tomorrow after a good night of sleep.
When I do nothing Leap starts, then I can also use the arrow keys to boot tumbleweed.
Gonna test this, almost cant believe it, making sure usb is not in.
We have a winner
Thank you malcom and mrmazda.
When I do nothing, after, turning on pc Leap starts
But from grub I can use the arrow keys, and then boot Tumbleweed.
I might even be able to boot that cursed os, but I am not in the mood to test this.
One thing I hate about windows is the update process.
You dont even get a change to say no, and I had not booted windows in months.
So first thing it did was updating and messing up grub. 
Maybe when I feel brave tomorrow, I might change this to Tumble weed to be the default. Maybe can do this from grub ?
