Big Sur signs me out when Air playing

Hi All,

Our VP recently purchased the newest Macbook Pro - it's running the latest version of Big Sur.

Each time he tries to airplay to a Samsung TV it immediately signs him out.

I tried:
Resetting network settings on TV
Resetting Paired devices on TV
Rebooting Computer/TV
Making Sure Computer/TV were up to date

I am able to airplay from Cellphone to TV

Thank you for the support.
