The Catholic Church has issued a warning to its clergy in Washington state: Any priest who complies with a new law requiring the reporting of child abuse confessions to authorities will be excommunicated.

This is not true. A therapist would be required to break confidentially if they became aware that their Client is going to harm themselves or others, or if they are mandated by law.
What someone already did in the past generally isn’t reported.
I find zero sources that agree with your claim.
I find several sources that indicate that therapists in all US states are required to break confidentiality when child abuse has occurred.

So either you’re talking about another country’s laws (in which case I’d like to know which country), or you’re just incorrect.
I’m in Colombia, where psychologists are required to report “human rights violations, mistreatment or cruel, inhuman or degrading conditions of confinement of which any person is a victim and of which they become aware in the exercise of their profession.”
