Hello coolsans!

I’m sorry to hear that you’re having trouble. There is a very comprehensive post concerning this error here.

However, this issue has also been known to be caused on some laptops with GPU switching software. If you have a laptop that uses something similar to the Optimus software, make sure that the launcher and the associated Epic products are set to use the discrete GPU.

Hi coolsans,

We haven’t heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you’re still experiencing this issue, please try the suggestion that I mentioned above then post back here with the requested info.

If you need anything else, feel free to ask.
