Global Temp Table inserts work in12.2 but fail in 19.17

I have a process that writes to a GTT with COMMIT DELETE ROWS. In 12.2 it allows for multiple recursions of the code to run without issue. In 19.17 it works on the first pass, but then throws "Failed executing statement (ORA-14450: attempt to access a transactional temp table already in use"

What can be done to revert to the old 12.2 behavior?
