Directly after update to hassos 3.12 my entire system is unresponsive. I do not know where to start.
running hassos as a VM in ESXi…
Can you access it via the command line?
Can you view the system and home assistant logs?
It turns out that together with/immediately after updating to 3.12 the error was introduced. I have deleted the custom integration of samsung tv and then the problem was gone. It seems that the error is in there. I will investigate further.
I raised an issue:
