Ive just discovered a similar issue, after several different fault solving attempts I discovered that starting any flight, in any ac, at cylw caused a CTD at the end of the load screen.
I uninstalled the market place version and tired again with the same CTD issue.
I searched in the folders and found another entry for cylw but this time from the FSSTUDIOS version of the same name. (FSIMSTUDIOS-AIRPORT-CYLW-KELOWNA) a 08 byte file.
I had purchased the airport via Orbx and also in the MSFS market place.
Ive deleted anything I could find with the cylw in the totle re-installed it from Marketplace but it still crashe to DT at this one location.
Please help.
