It's likely going to take a lot of work on our end to find the issue but we will dig deep. Please be patient as we have zero ways to reproduce the issue so we will need to likely breakdown the spawning tech and build it up again.

When you do a driver install for your GPU be sure to do a "clean" install. This will remove the old drivers and issues and do a complete fresh install. You should know if it works because you'll likely have to restart and you won't have the full resolution of your monitor as it is installing.
This error is very likely caused by driver complications so I just need to be 100% sure you've got the cleanest version possible.
