Simulation crashes whenever Lunar Surface Ops is selected from Demos

[connorjak]

Discussed in https://github.com/SimDynamX/SpaceTeamsPro/discussions/55

^{Originally posted by **hayyamiqbal** October 31, 2024}  Demo doesnt even load before giving this error. Tried this on 2 different devices with 16GB & 64GB of RAM i9. Tried with both Personal & team account.

I'm also having a hard time getting anything to run without crashing immediately. For Lunar Surface Ops, the end of the log looks like this:

We've made some changes to the core code during STU Lunar SAR which may disrupt running some of the demos. SolarSystemExplorer is the only demo that is guaranteed to work all of the time while in beta.

[connorjak]

Please keep submitting bug reports like these as you encounter issues though, this helps us find and fix them to ensure we have more working demos!

I was going to mention the sim config demos not working on my desktop machine as well. The stp program/app will crash and I get Python crash/error notifications so I know something in the Python backend is crashing. But stp will crash and send me to the Unreal Engine crash reporter.
