Another brief, if somewhat promising, update.
After some troubleshooting and a little more research, it does appear to be related to running multiple monitors with nvidia graphics. I was unable to find a fix.
However, reconnecting my USB-C docking station and doing a brief restart on the box appears to have somewhat alleviated the issue. I'm now able to occasionally launch Forge without crashing. Not an ideal fix, but at least I can play.
For those interested, I'm currently running nvidia driver 440.44. I'm hopeful future updates to this and the Display Link driver I'm using for docking station support will fix this issue fully.
If I find any more information, fixes, or have a marked change in performance I'll be sure to update this thread for posterity.
