bureaucracy chaos before moving to Iceland

Really would appreciate Your help in the following topic:

I want to move to Iceland in the beginning of 2028. I am a social worker and EU citizen.
In preparation and to not arrive without knowing if I can work in my profession (regulated in Iceland), I applied at the ministry of help for a licence to practice. Appart from requiring 1000 different documents that are hard to get in Germany (as the profession of social worker is not regulated here and not listed as a health care profession), now they want me to provide a kennitala. The þjóðskrá in return told me, I can only get a kennitala with a domestic residency and that a systeþ ID would be the only thing I could apply for in the beginning. The System ID can I get only whem I am lready in Iceland and i need to apply in person.
Anybody been through this process alredy?
Is it even possible to get the licence to parctice before I move, or do I really need to take the risk of moving, leaving everything behind and them getting rejected?

Thanks in advance for Your help!
