TeamViewer 13/14 sometimes do not launch on Windows startup

I turn my PC on in the morning before leaving for work (I keep the monitors off) and I only find out that the software sometimes doesn't launch when I get to work.

I can launch it manually without issues and there's no reason for it not to be starting up.

Every other piece of software launches perfectly and always has.

This is a TeamViewer issue, somewhere.

This happens with TeamViewer 14 but also happened with 13 and, though I can't be 100% sure, 12.
