Hi!
Hostapd file in not complete, you just shared the header, also I’ll recommend to use custom kali for the course sake and if you want to use anyother kali version for your own work is ok. This because you’ll need to be roor user to run this attack properly and using custom kali will also have the proper version and tools installed on it.

Also you didn’t mentioned you adapter model, can you share a screenshot with the results of iw list?

Thanks!
Diego
