MSFS 2020 Won't Launch since World Update 4

Since installing World Update 4 for Microsoft Flight Simulator 2020 the software won't load. It hangs on the splash screen and won't finish loading the program. I have also installed the most current update and still no progress.

I am running Windows 10 Enterprise with the latest updates installed and Microsoft Store updates also current. I have installed the most current graphics drivers for my nVidia GTX 1080 TI GPU.

My system:

Intel® core™ i7 CPU

24 GB Memory

1 TB SSD

I have run the repair program for Microsoft Flight Simulator 2020. I have run all of the utilities on my computer to clean the system and scan for viruses and every other program works fine except Microsoft Flight Simulator 2020. Please help

Could your anti virus program be blocking it? Might be worth adding an exception just in case.

A few months ago, my MSFS started doing the same thing. It turned out to be Microsoft’s own “Defender” that was preventing MSFS from launching. I added the MSFS folder as an exception and it solved it.

MS did correct this shortly afterwards though, but maybe your own antivirus is doing the same thing? Might be worth checking.
