Sorry, haven't had time to investigate this bug yet. Been very busy with a long list of them
Looking deeper, this looks to be a permissions issue. Could you try running your simulator as administrator, and see if it makes a difference? Either that, or possibly some sort of anti-virus interfering.
I had this crash and error message 3 times when importing TS3 into the VC. Set P3D v4 v 4 to run as administrator in the properties and did the same with FlyInside and also set the permissions for TS3 in windows 10 firewall. And the problem seems to have gone away, haven’t tested it much but pre IOU’s lay it crashed immediately I tried to import TS3 so it probably fixed.
Overall a great bit of software, wouldn’t use VR without it.
