Incorrect MAC address format

[ZAAJR]

I am getting an "Incorrect MAC address format" error when trying to turn on a Samsung TV. It used to work in previous version, but no longer working in:
Home Assistant Core 2022.6.5
Home Assistant Supervisor 2022.05.3
Home Assistant OS 8.1

Full error message shown below. I am not sure what format the MAC address should be in in the configuration.yaml file. I have tried separating with colons (:) and with no separation between the pairs.

Configuration.yaml

media_player:
  - platform: samsungtv_tizen
    name: lounge_tv
    host: 192.168.0.62
    mac: 54bd7933954e
    api_key: xxxxxxxxxxxxx
    device_id: xxxxxxxxxxxxxxxx

Also tried

 media_player:
  - platform: samsungtv_tizen
    name: lounge_tv
    host: 192.168.0.62
    mac: 54:bd:79:33:95:4e
    api_key: xxxxxxxxxxxxx
    device_id: xxxxxxxxxxxxxxxx

Try

 media_player:
  - platform: samsungtv_tizen
    name: lounge_tv
    host: 192.168.0.62
    mac: "54:bd:79:33:95:4e"
    api_key: xxxxxxxxxxxxx
    device_id: xxxxxxxxxxxxxxxx

I use dashes in my MAC address format. This is my configuration below which works just fine.

`media_player:

• platform: samsungtv_tizen
  host: 192.168.1.12
  mac: 1a-2b-3c-4d-5e-6f
  name: "Living Room Samsung TV"
• platform: samsungtv_tizen
  host: 192.168.1.14
  mac: 11-2a-3b-4c-5d-6e
  name: "Bedroom Samsung TV"
  `

I also think using the quotes and colons as @numbnp used is also valid, as I may have used that at one time.
