Could not connect to DisplayLink
 

I have a 2018 MacBook Pro running Mojava (10.14.1) with 2 external monitors and the DisplayLink driver v4.3 beta 6. Occasionally when I connect both monitors using a dongle they both work as expected giving me 3 displays in total.

Other times however when I connect my monitors it shows the HDMI monitor with no issues but the other one gets mirror to my laptop screen and I get the message "Could not connect to DisplayLink".

This erratic behaviour is extremely frustrating and I can't seem to find a fix for it. Has anyone encountered this issue? Can anyone suggest possible solutions?

This is similar to the problems that many on 10.13.6 are seeing with the 4.3 and 4.3.1 drivers.
