addons: OpenThread/Multi-Protocol addon starts erroring and bootlooping after a couple days

Not entirely sure of the root cause, just had everything working last night, woke up and it’s all broken. 3rd time this has happened now and the only solution I’ve found is a full power down (even rpi reboot doesn’t help). Here are the addon logs from a fresh addon restart. It just repeats the last two times over and over until the watchdog restarts it continually.

Full log after a fresh restart:
