It's "Adolescence". Each episode is single shot. Also other than Stephen, the child actor's performance in it is outstanding!
Holy shit! I'm glad you mentioned it here because I was going to.
Also, for more continuous shots, the chase sequence in Adolescence is linked here - https://youtu.be/VQnyL7pagYY?si=oZiJJlTbnoyE0bBa and the behind the scenes here - https://youtube.com/shorts/dQ3F6qs3L0U?si=EEWEQOPKqh7bxsOy
But, really, the whole show is a classic. Highly recommended.
Then, of course, there's the continuous shot in True Detective Season one involving Rust Cohle. "30 seconds in and out. 30 seconds" - https://youtu.be/vnRTITzYnXs?si=tJZQ7BNAzPmOGsM-
