          I have also problems since the last HA Update. The Add-On does no longer start. Once i restart it it will immediately shutdown. I got those error log

I get this error as well.
If the roborock is running, then I start go2rtc, then it works fine. As soon as the roborock docks, the plugin fails again.

For a temporary workaround, you can use an automation like this

alias: roborock - restart stream
