Hi,
Thanks for the screenshots and the additional information.
I´m 100% sure this is an issue with either the 3rd-party scenery or another scenery package you have installed. I would first try removing or disabling the 3rd-party LPPR scenery and then try it again.
That has nothing to do with any SU … it is an incompatibility issue with a package on your system.
