Hi Alexgarcia,
True, I noticed my Prepar3Dv4.5 CTD after Windows update on 03rd July 2020 and after updating Nvidia Drivers to version 451.67 on 9th July 2020 from 451.48. So not sure about what was happening the cause to CTD of my flight simulator. First I rolled back Nvidia drivers to June version 451.48 since I had not problems in June with Nvidia Drivers and with Windows. Now my flight simulator is working for long hours with no crashes, hence I did not uninstall any July updates of Windows. Though in the Event Viewer Administrative Events, Errors are keep appearing
