ASUS MB168b not working with MacOS Catalina

[hano]

For years I have been using my Mac mini with MB168B as the main screen. Then, all of a sudden, when I upgraded to Catalina and then installed the driver needed for my USB screen to work, all the screens I have stopped working, the HDMI ones, and the VGA ones. I tried many screens, contacted Apple and then, after uninstalling the driver, all my other screens except the MB168b worked fine.

I installed DisplayLink Version 5.2.1as recommended by ASUS, with no luck. I then installed 5.2.4 and also with no luck.

In general, the monitors works 1 time out of 10 restarts, I don’t know why!
It’s worth noting that I also followed this guide https://www.asus.com/support/FAQ/1041769/

Would you please help me get this issue fixed?
