For 2024, you will file a part year resident tax return for both states.
On the CO return, you will only calculate CO tax on your income from 1/1-6/7. You will claim a refund of the excessive withholding (taxes paid between 6/8 and 12/16).
On the NC, you will only calculate NC tax on your income from 6/7 to 12/31. You will probably have to pay an underpayment penalty for not having enough withheld.
For 2025 onward, you will file only an NC resident return.
