[Linux] AirSimExe no longer working

[AlessandroSaviolo]

Hi,

When running ./AirSimExe.sh (either in window mode or without) in Ubuntu 18.04, the simulator crashes without even loading the starting environment.
I have been using Airsim by couple of months and it has always worked without any problem. I've tried to download again this and Airsim repo and to reinstall airsim and airsimneurips packages. But, it keeps crashing without showing anything.
I've also tried to use it with and without rendering but it produced the same error.
The errors that appeared in the terminal are the following:

Thanks in advance for any help!

The problem was Ubuntu not killing the process correctly. Had to use system monitor to find it and kill it. Closing the issue.

May I ask what the process name was? I'm running into this exact same issue but I haven't been able to resolve it.

[AlessandroSaviolo]

Use the command pkill AirSimExe. Hope it helps!
