Sāʾat is a feminine singular perfect verb; its attached -ki is a second-person feminine object pronoun. Khalīqatun is a delayed, nominative, indefinite subject. The trait responsible for the displeasure is revealed at the clause’s end.
Minnī links that characteristic to the speaker. The resulting sense is “some quality of mine has displeased you”, not “you spoiled something belonging to me.”
