OpenThread Border Router crashes after some time after update #4230
Description
Describe the issue you are experiencing
I am using HA OS on Raspberry Pi 5 with Smlight SLZB-06M over ethernet with OpenThread Border Router add-on.
After some unclear update (Core? OpenThread Border Router?) I got the following situation: After some hours of running the add-on (OpenThread Border Router) is crashing and not starting anymore.
I notice this as my Thread/Matter Devices are going to unavailable.
To recover I manually have to start the add-on. I am using this (the same) setup now since over one year and did not have any issue before, it was completely stable. I cannot say which update caused this issue.
There are also other topics reporting issues with this add-on, but seems to be different than mine (not starting) and I am not sure if mine is related:
#4210
I tried with OpenThread Border Router Version 2.14, 2.15.0, 2.15.1, but same issue with all version.
By state of Thread/Matter devices:
In the attached logs add-on crashed around 11.11. 22:47 and started again on 12.11. around 5:45/6:05.
And another on 14.11. 2:29 and back on 14.11. 6:23/6:29.
