I tried using SKA but still DBI tells me this:

Hmm… I had no problem running FB3 on HOS 18? 19? Is this a recent update?

You could try using a different installer.
Yes, it's latest 2.0.0 update that fixes stuff and add new exercises bug-fixes.
1.3.0 it's the best one since that works on 20.5 and below
 
Since you're using DBI, I believe the process goes like:

  1. Export SDK from an older game/update
  2. Import SDK to this game update

I recall that some versions of DBI either have import/export SDK disabled or broken, so be aware of that.

For reference, here's what that process looks like if done manually:
