Integration crashes Home Assistant
Adding the integration to my configuration makes Home Assistant crash instantly at boot. It tries to reboot immediately after but keeps crashing. Meanwhile, other integrations do keep running such as Bitwarden. When I first tried to configure the integration and messed up the host IP, it obviously did not connect to the TV, but it also did not cause the crashing. After I properly configured it, the code did seem to work and control the TV for a second, but caused a crash very soon after. The TV is a Tizen Samsung The Frame 2020 50".

**Configuration.yaml**
`   - platform: samsungtv_tizen
     host: 192.XXX.XXX.XXX
     mac: 64:XX:XX:XX:XX:58
     name: "The Frame [lan]"
     api_key: !secret smartthings_hacs_tv
     device_id: !secret device_id_tv
     is_frame_tv: true`

**These are the last log events (I could see) before a crash:**
