The main issue is visible in both the DisplayLink and the system logs: at some point the USB 3 part of the hub in the Targus dock disappears.
In the DisplayLink logs this is shown as transfer errors and device unavailable. In the system log you can see transfer and wake errors in both USB2 and USB3 devices and then only the USB2 part of the hub is reset while the USB 3.0 part of the hub is longer there, together with the DisplayLink device.
USB 3 is difficult hardware-wise because of both higher speed and more advanced power management so looks like something is borderline in your use case and fails.
I'd think about the USB-C adapter as the first thing to try and replace, but you may also want to try with a different, shorter, USB cable between the Targus and the adapter.
A separate issue is with the monitor. I'm seeing 8 different monitor description files so unless you are trying eight different monitors it is likely that there is a problem connecting to the monitor. Most likely the connection, I'd check the DVI cable.
Bes regards,
