Hey guys. We recently came across a curious new issue with the FFMODStudioModule. On engine start and shutdown it throws Error: System::getBus(bus:/, 000000364A17C530) returned error 74 and subsequently error 30. My understanding is that its fundamentally a nothingburger since this only happens when the module either hasn’t been loaded yet or already started the shutdown process. Audio works fine, no issues there. Where the issue is getting tangible though is using Rider, like my team does. These errors are resulting in breakpoints which is driving my programmer insane.
log showing error on shutdown:

Any advice on this issue?
