Thank you for reporting a bug to Unity. Our investigation indicates the issue originates from a third-party asset, plugin, or service, rather than Unity itself. Because the problem lies outside our codebase, we're unable to address it directly. We will close this case as a third-party issue. We recommend contacting the vendor or maintainer for support. If you have evidence that the issue is within Unity, please share it and we will re-open the investigation.
How to reproduce:
1. Open the attached “IN-148601” project
2. Navigate to File > Build Profiles
3. Build the project and copy its path
4. Launch the build from the command prompt with arguments "-force-d3d12 -screen-fullscreen 1 -window-mode exclusive"
5. Press Alt+Enter 2 times to enter fullscreen mode
6. Rapidly switch focus by pressing left clicking on a second screen then Alt+tab back to the build (do this for ~1 minute)
7. Observe the crash
