Game crashes just before the main menu after 5th May hotfix. (self resolved)

Platform: PC (Steam)

Description: The game loads and goes through the start screens but a couple of seconds into trying to load the menu (tape symbol spinning) the game crashes with a crash report. This happens on two different computers and two different accounts. I have verified the game files on both and completely reinstalled the game on one. It has made no difference.
This only started after the update installed today 5th May.

Steps To Reproduce: Every time I restart the game I get the same issue.

GPU: NVIDIA GeForce GTX 1060 6GB (PC #1)
NVIDIA Quadro M4000 8Gb (PC #2)

UPDATE! This issue was just fixed by deleting the saved game folder (after backing up) and allowing the game to re-sync with the Steam cloud.
