Crash on startup

[FoxTwo]

Everytime I try to launch PR, it tells me "PR:BF2 has closed, cleaning resources" or, when I try to launch it windowed it gives me error window "Debug assertion failed! Module: RendDX9 text: Unknown DynamicOption value 800x600"

Make sure to install DirectX 9, .NET framework and have all latest window updates

Download DirectX End-User Runtimes (June 2010) from Official Microsoft Download Center

I have DirectX 12, so i cant install 9. I have .Net6.6.1 and latest windows 10- 10586.63

Disabling Windows Defender using a third party app worked for me.

Edit: worked for two start ups before it started breaking again.
