MSFS 2020 CTD During loading, event viewer says "190_E658703.dll_unloaded"

So I recently upgraded from a 1080ti to a 4070ti. Yesterday and earlier this morning FS2020 was working great. But, when I got home from work I tried to fire up the sim and it crashed right before it finished loading. No error message or anything- the sim just shuts down. Here is a list of things I have tried so far:

1) Starting the sim in Safe Mode. This only made it crash faster

2) Removing everything from the community folder.

3) Uninstalling everything that runs while the sim starts, namely GSX/Couatl, Navigraph Simlink, TDS GTN, and FSUIPC.

4) Deleted C:\Users\myname\AppData\Roaming\Microsoft Flight Simulator because it seemed to work for someone else who had the same issue.

5) Looked at event viewer. It said "Faulting module name: 190_E658703.dll_unloaded, version: 2.7.10.0" I thought might be fixed by installing the latest microsoft .net framework, which I did but it's still crashing.

5) Did a full clean reinstall of the sim.

And it's still crashing! I'm at my wits end- I've never had the sim crash repeatedly like this and I have no idea what could have happened because I didn't make a single change to my system from when it was working this morning to when it stopped working this evening. I have no idea what 190_E658703.dll_unloaded is referencing and can't find anything about it online.

I would be really grateful if anyone could help because I truly have no idea what's going on here.
