We experience macOS kernel cache issues. Most likely old incompatible kernel extension is still loaded.
Can you help us to verify our suspicion?

Please do following experiment:
- Uninstall DisplayLink software
- Reboot
- What is the output of command(empty output means it is OK):
kextstat | grep DisplayLink

Give us an update, and follow that article if "kextstat | grep DisplayLink" returns non empty output.
2. Please follow steps from that article:
https://support.displaylink.com/know...lay-is-working

After uninstalling and a restart, the output is not empty:

kextstat | grep DisplayLink
43 0 0xffffff7f8276c000 0x10000 0x10000 com.displaylink.driver.DisplayLinkDriver (4.3 (124)) 21BA08D2-055E-380E-B526-1798079CF68D <42 13 6 5 3>

It seems indeed to be a cache issue. How to burst the cache?
