Maya 2020 Fatal Error after scene load

[Anonymous]

Hello all,
I am having issues with a specific .ma file (I have confirmed that other scenes work fine, but several of the most recent iterations of my scene do not open, all with the same error message).
I am sorry if this is a repost, I did spend several hours trying to find solutions in existing forum posts before I posted myself.

I have attached a screencap of the Output Window at crash.

Prior to issue:
- No issues prior to this morning (worked on the scene last night/ all day).
-I thought issue had to do with Arnold plugin, so I have already tried, reinstalling said plugin, updating GPU driver (NVIDIA GeForce GTX 1070), adjusting "TdrDelay" and "TdrDdiDelay" Registry keys (both to [120]), resetting Maya 2020 preferences (renamed "pref" folder and selected "Create Default Preferences" upon Maya startup), and reinstalling Maya (through Windows control panel. I doubt this was a 100% clean reinstall).
- I was getting the "00:00:00 1126MB WARNING | [mtoa] [<built-in>] [node aov_write_vector] Assigning temporary node id..." error, but reinstalling Arnold/ Registry edit seemed to deal with (this) issue. New issue as seen in screencap.

- Importing .ma file to new scene also causes crash

- 

If anyone needs additional information from me to help me solve this issue, I will try to provide what I can. Any/all help appreciated. Thanks in advance!

EDIT: Crash recovery files are successfully created, but suffer from the same issue as original .ma file.
