Apologies upfront if the following response sounds harsh, but your post shows a somewhat strange lack of information on a number of details and I’m wondering if that’s by intention.
Please read and always follow general advice on posting as explained here.

As installing with clonebranch=stable does work in general, something about your system must be different so I suspect you have unmet prerequisites or unsupported components or procedures (SSD? USB boot?) that you don’t tell about.
If that’s the case you should at least be fair and tell us.
First, fully name your goal. Is it to get OH2 installed ? If so, why ?
clonebranch=stable is not a goal by itself so you’re making us victim to the XY problem (see 1st link).
What do you mean, did you use the image or not ?
Fully describe the steps you used for install, please.
Installing Raspi OS yourself then manually running an unattended installation is pointless. If you did, why ?
Read the docs please, /opt/openhabian/docs/openhabian.md in particular (docs on openhab.org are a copy of that).
Before you poke around yourself. Make sure you meet the prerequisites first. There is also a debug guide seems you have not even read that as it says that to be/become of use, any debug log needs to have debugmode=maximum.
