**Premise false — no cause of death to report.**
Jason Arday is alive; he holds a professorship at Cambridge (sociology of education, appointed 2023 as one of the youngest Black professors there). No credible story reports his death, so there is no "cause of death" fact to retrieve or state.
**Contradiction flagged:** the question assumes a death event that hasn't occurred. Answering "cause of death" under that false premise would be fabrication.
Missing/needed to proceed: a specific source (URL, headline, or outlet) claiming his death — if you have one, share it and I'll check whether it's satire, a mix-up with another Jason Arday, or misinformation.
