Usually this is caused by being careless about search_path assumptions
in your functions ... but with no details, it's impossible to say
anything with certainty.
No, in this case it is not:
Function A using function B.
Сreating function A before function B results in a compilation error.
Function B has no dependencies and is generated without errors. The second run of the circuit creates function A.
If I could specify a function dependency, it would change the order of recovery

Otherwise it couldn't guarantee that the rows were restored with the same
values of the identity column that they had before. I recall that we
had some bugs with GENERATED ALWAYS in early v10 versions, but when I try
it now, dump/restore of a table with an identity column seems to work
as expected. What minor release are you using?
