Unable to screen share MacBook Air M2

I have a MacBook Air M2 that I’m trying to connect to my Samsung TV via AirPlay. This used to work up until recently but now I can’t even see the TV in the Displays in Settings on the MacBook. It’s also not coming up when I click the Screen Mirroring button in the Settings menu in the taskbar. They’re both on the same WiFi network with AirPlay enabled, the firmware on both is up to date.
