I manage to fix it by deleting the Default.fxml and Default.wx files from \Documents\Prepar3D v4 Files folder. Thank you very much for your help!!!

I already try it by dissabling OLC NA through Scenery Config Editor and P3D runs witout any issue.

NO! I tried also deleting the Prepar3D.cfg, so the system can re-create it, but same result.

I uninstalled KB4038788 but had no affect. The problem still exists.

I also included the DxDiag file form %appdata%\Roaming\Lockheed Martin\Prepar3D v4. dxdiag.txt

I get a CTD after installing Open LC NA in P3D v4 with hotfix 1. I get to the scenario screen but when I OK and then I get a KERNELBASE.dll error. Any idea.
