I just found this very helpful post which may help you:

openHABian 1.8 release

I ran into excactly this problem today. I only wanted to update my OpenHabian 3.x System with the newest fixes and got an unusable Openhabian 4.x with old OS and Java11. Nothing got me back to a working system. I completely recreated a new Openhabian from scratch (flash SD card), did a first initial config of the new system and then restored a OH backup file. I needed to do the restore twice, because of errors in first restore (whyever). I had some hickup saving the old backup file into the new OH backup directory due to access right restrictions on the backup directory. I managed it saving it first to another dir and then ssh in and move it with a sudo command. Hope this helps others to succeed.
