I was updating an asset USA SP Class GS-4 Steam Engine kuid2_59906_4449_1.cdp
There was an error loading dependency: USA SP Class GS-4 Engine Rear Bogey <kuid:59906:50011>
Failed to load child images for texture file: 'sp_classgs-4_4_8_4_body.texture.txt'
Could this be causing the troubles I was seeing?
I took the version of the route that I had not installed three trains and a piper cub airplane and could open that in Driver. One of those trains had a GS-4 in it.
I was then able to Edit Trains and add the three trains and Piper Cub and run them all without experiencing the white out.
Question: Should all my locomotives and other rolling stock be installed in the session-layer? Could this be causing problems?

Definitely put all rolling stock on your session layer. There have been reports of issues with putting rolling stock on the route layer, but I have never experienced that. Sessions are things that are dynamic such as rolling stock, therefore, put the trains there. I believe in KISS and I've done it this way for years with zero confusion.
If this content has been installed from CDPs, and it has been, it'll appear as modified in Content Manager rather than Built-in, Payware, or Installed from Download Station.
It's possibility that this asset is corrupted, but that should not stop the program from working, or your route from loading, it may however, break a driving session by being missing. Delete this dependency and reinstall from your CDP. That will repair the asset since this should not have this error.
Sometimes errors will appear in content after running an EDR. Viewing the errors and warnings generally will make them disappear. Why this happens, I don't remember as it was explained once to us ages ago.
With my 1.5 TB of content, an EDR will take about 4 hours on my regular hard drive, therefore, your 100GB database shouldn't take as long to repair as it did. Hopefully your hardware is okay. There are things I can think of that can cause that off the top of my head: A full disk, a highly fragmented older-type disk, a failing disk, malware scanning, background processes other than TRS19 running - watching videos, listening to music, browsing, malware infections, etc.
