Airsim City Environment not starting after Windows update

[MartinAFHWS]

Hi,
I've successfully build Unreal Engine and Airsim on Windows 10 and would like to use the city environment with moving vehicles and pedestrians for a drone (px4-SITL) algorithm to avoid crashing into the moving vehicles and pedestrians. Before the last windows update i could launch the city environment 1.2.0 - 1.2.2 but now it doesnt start. It gets to a loading screen which is completly black(which is normal) and then just shuts down. There is no Error Message popping up.

I already tried to start other versions of the city environment and the blocks environment but none of these are starting correctly. I also tried to use different ue4 versions which also didnt work.

unreal: 4.18 and 4.22

Logfile of City environment 1.2.2:
CityEnviron-backup-2019.06.14-13.49.52.log

Thanks

Hi Martin.
Have you tried the solution suggested here?
https://answers.unrealengine.com/questions/758236/all-my-plugins-nodes-get-call-unknown-function-err.html

The issue was resolved by clearing the contents of C:/Users/{system username}/AppData/Local/UnrealEngine.

I was able to run the city environment without issue. If the above fix doesn't work, can you let us know which exact Windows 10 version you're using?

Unfortunately it didn't work.
My Windows version:

Edition: Win 10 Pro
Version 1809
OS Build: 17763.557

I'm afraid it must be a local dependency issue. We're able to run the latest environments (including city) on Win 10 v1809 - 17763.557

Thank you for your help.

I found the issue. It was a faulty airsim settings.json file, which somehow didnt show up in the log file.
