To be frank, I was well aware that a stopped worker on 241 has the issue on the first start after updating to 243. But with the second start the...

In my tests, the upgrade from 242 to 243 went smoothly. On PROD half of the running workers successfully completed the 241 -> 242 -> 243 upgrades without any issues....

Fixed by #2081
