You can also try deleting your rolling cache... I know stale rolling cache has caused issues for others in the past:

I typically delete the Nvidia shader cache with new updates as well, but not sure if that is important with AMD cards. Hopefully you can find the root cause, strange issues like this are always the worst. Did you try with an empty community folder?

Yeah, I deleted both the RC and cleared all nvidia shader caches just a couple of days ago prior to installing SU6.

From google AI: In Microsoft Flight Simulator 2024, TIN stands for Triangulated Irregular Network. It is a 3D digital mesh technology created from aerial photogrammetry.

I'm not sure if you're asking for others to check in, but I have been flying around SoCal for the past week with no issues. And that includes the iniBuilds KLAX. Just to be sure, has the OP cleared out the Community folder and turned off any external add-ons in order to test the system?
