For anyone having the issue of scenery objects lists empty and after that receiving an error “failed to load from file” there is an issue with an official expansion that is causing this error.
Similar to what is shown here: Scenery Objects Empty
You can solve it troubleshooting with PROCMON the process flightsimulator.exe and find which BGL is failing to load. In my case I’ve found that the expansion Oceania, more specific the Pohnpei Airport scenery with the file OCE_APT_ptpn_ModelLib.bgl was failing to load.
I’ve removed this airport, in fact I’ve decided to remove the whole Oceania expansion, and it just stopped giving this error and the scenery objects now finished the loading and completed successfully.
If you have this issue, troubleshoot and monitor File operations for the process flightsimulator.exe using procmon.exe which is a sysinternals/MS official tool to monitor process and start capturing when you open the Inspector > Scenery and determine which file is giving you the error DEVICE DATA ERROR or something similar.
Hope this helps to anyone having this issue. It took me few hours to resolve it.
