MSFS 2024 Default Nav data broken after installing 2513 Rev 1

Hi,
Possibly, you have a third-party scenery issue somewhere. As you can see in the forum, there are no other reports about it, so it seems to be isolated to your system.

I would recommend following these FAQ steps:

FAQ - MSFS2024 (SU3 and above) - airport, procedure, waypoint, 3rd party & flightplan import issues

Cheers
