MacBook Air M1 - Screen goes to sleep while streaming TV

It doesn't happen all the time but sometimes when I'm streaming on Xfinity or Netflix, the screen will start to go to sleep. The sound continues but the screen goes completely to sleep! I've checked the settings even though it's not happening all the time, and the settings seem fine. I've updated to the latest Ventura, but it's been happening since before Ventura, so it doesn't appear to be the operating system.

Anyone else experiencing this?
