macOS 10.15.6 update broke DisplayLink + 2 External Monitors

Displaylink stopped working after update 10.15.6. And the 2 external monitors stopped working.(Connected two 4K@60Hz via D6000 Dock (HDMI)+ (DisplayPort))

After removing and installing latest DisplayLink driver, Only one monitor is connected but at 30Hz. You need to open the displaylink manager to get the other monitor working. After opening the displaylink manager both monitors are connected but one of them is still at 30Hz.

So I uninstalled all the Display link drivers and installed the below. After the install and restart both 4K monitors are working fine at 60Hz.

Installing the DisplayLink USB Graphics Software for macOS (5.2.5) solved the issue
