Once I located the dkms install by dpkg -S /var/lib/dkms and removed it with sudo apt remove dkms, I no longer have issues. The point here is that I wanted to be rid of those evdi log files and I didn’t know the name of the package that hosted those files. Which is why I used the dpkg -S command to locate it and then proceed to uninstall it.
As a kernel install/upgrade issue I’d consider it resolved. As a bug in EVDI preventing DisplayLink drivers from installing, I would consider it unresolved.
I have no need for DisplayLink. It was a half-assed solution to make multiple external monitors work over only one Thunderbolt lane (back in 2019). There were cheap docking stations that could connect two monitors (using DisplayLink) but were using only one TB/USB-C connection. It had performance issues and I recall that XServer had issues with it. Don’t know anymore because I don’t use it today.
This has not resolved the other issues I’m working on and I have now tried different kernels. I’ll post more info on that in the other thread.
I mark this as the solution combined with the instructions in the prior post from @1fallen
