I am facing the same issue. I have ported a game from 5.3. The abb file generated with 5.3 had no errors, but with 5.4 I get the same error as you. The weird thing is that I have not changed anything related to the ads between the two versions.

I’d be interested to hear if anyone else if facing the same issue or has found a solution.
