Mostly posting this for anyone else getting a crash after allowing Windows Updates to get applied. My BG3_DX11 was running fine, until I let Windows Updates happen. Then BG3 crashes every time I enter the game. I thought at first it was mods (barely have any), but rather than gank my mods I just rolled Windows Updates back to earlier that day and BG3_DX11 works perfectly again.

The Windows Updates that applied was Cumulative .NET Framework for Windows 10 (KB5034685), the usual Defender patches (KB2267602) and Cumulative Update for Win10 22H2 (KB5034763). Not sure if these were truly the culprit.

For any tech heads out there, here's the Event Viewer intel:

I'll send this along in a bug report too, but just in case you are suddenly crashing after Windows Updates this week.
