Hi, (I am not part of Laminar)
Best to wait for someone of the Laminar team to respond BUT I can give some suggestions
Whoa man, you have a lot of custom scenery installed + a ton of plugins.
To me personally , the issue looks to be coming from LFRB, LFMP, LFMK, LFJL, EGTK, EGBJ
Try deleting your preferences files inside the folder, which resets the sim.
This is going to sound horrifying, but run the sim without any add-ons installed and fly the same route as you mentioned above.
Try those things, but soon someone from Laminar will respond to you. Hope this somewhat helps you. STAY TUNED!
