What are your setting for Live/AI traffic, multiplayer and generic models for AI traffic and multiplayer. Try with all of these off - at least that might eliminate these as potential causes. Some users have also had crashes by having the ATC set to Azure. Again, you could try that to eliminate that. There is a long thread here that is worth working through (looks like you’ve already done a lot of what’s suggested, but worth a double check maybe)
EDIT: I think you said you are using VR. Many people report that nVidia divers 457.30 work much better with VR thatn the more recent 416.09 or 461.40
