Description

I think this could occur anytime but is probably very rare. However using this plugin from the reported UDN makes it much easier to repro as they are calling FMacApplication::ConvertCocoaPositionToSlate() on a non-game thread.

Steps to Reproduce

See more info at:

[Link Removed]

  • Install and enable the IILAD plugin
  • Create a texture asset
  • Selected Edit with ILIAD
  • Use the ILIAD window editor.
  • Observe crash due to non thread safe use of TSharedRef<FMacScreen>.
