On our CD environments we have a Deployer and a Deployer Worker Service all running on Windows Server 2012 R2. We are running Web 8.5 with latest Hotfixes.
When restarting the Deployer Worker Windows service, it sometimes fails to startup with an exception:

This particular behavior happens ~ 0-1 time out of 5 restarts causing all deployments to fail. Usually the service starts normal without errors and is also working like expected. This cant be reproduces 100% as it appears random.
Did anyone have the same problem already and knows a fix for this?
