The other day I mentionrd that I did not get any CTD’s…well I did not until today and all around the London UK area. Nothing has changed except the last European update (France, Belgium, The Netherlands and Luxembourgh) and I also had a update last thursday from Asobo which was not very big to rectify some issues with that last update. So the short of it is I cannot use UK2000-Luton, Orbx Shoreham and a few others. Houston…We have a problem now! Anyone with any Ideas? 
Most likely one of your mods is conflicting with the London Photogrammetry. Check if there are updates available to them. Should be, since the UK world update has been out for a while already.
To keep the forum organized, please use the #bugs-and-issues subcategories for seeking helping on CTD, bugs and issues. Before posting, search the forum to see if a topic already exists as we do not want duplicate topics.
Thank you.
The culprit…ORBX - Shoreham. Pay for something and it screws with MSFS2020 (wonderful). The joys of addons. 
OP has found the issue.
