If you moved to Seattle in 2022 with the intent of making WA your new permanent home, then for 2022 you would be considered a part-year resident of each state. The income you earned as an OR resident, plus any OR-source income you might have had after the move, would by taxable by OR for 2022.
For 2023, you are also a part-year resident of both states. You were a resident of WA until you moved back to Portland. During your period of WA residency, you would only be subject to OR income tax if you had any OR-source income during that time. Any income after your move back to OR would of course be taxable by OR.
