Please explain your issue is in as much detail as possible.
I load the game from Steam how I always have, and my mouse turns into the blue loading circle and the screen goes entirely black and never progresses. When I ALT + Tab I can see that the crash message popped up, but I cannot select it to read it. I have not done any updates to my system or drivers since the last time the game worked about 5 days ago.
Have you tried verifying your files?
No

Have you tried verifying files though the game properties in Steam? It often helps with issues like this after an update.

I agree that's the first step to try.

I also see this in the crash stack:

C:\ProgramData\Microsoft\Windows Defender\platform\4.18.1905.4-0\MpOav.dll

Which is a first! Add BattleTech.exe to the exceptions list of Windows Defender, in particular add it to the Ransomware "Apps Allowed Through" list.

And you should update that nVidia driver:
