Unreal Engine Causes a Screen Blackout (Screen Totally Black)

When running Unreal Engine 5.5x, my screen goes black. I can hear background music or video playing when this occurs. I can still actually use the keyboard to perform actions as if I am blindfolded. My screen goes completely black.

PC Build:

  • AMD Ryzen 9 9950x CPU
  • 2 x 48GB (96GB of DDR RAM with an AMD Profile - EXPO) 5600 MHz
  • ASUS ROG TUF 16gb VRAM OC GEFORCE RTX 4080 Super GPU
  • ASUS ROG CROSSHAIR X870E HERO Motherboard (1st PCIe slot)
  • Lian-Li Edge 1300-watt Power Supply
  • NZXT RGB Elite 360mm 2023 AIO Cooler
  • 8 additional Lian-Li UNI TL RGB Fans (LCD) 140mm
  • 2 x Samsung 980 Pro PCIe 4.0 NVMe M.2 SSD Drives (2TB / Slot 1 & 4TB / Slot 3)
  • Elgato 4K Pro Capture Card (2nd PCIe slot)
  • PC Case: Lian-Li 011 Dynamic EVO XL Tower / Case
  • Unit is connected to a CyberPower 1500VA UPS
  • Samsung G9 Ultrawide Curved 49inch OLED Monitor (240mhz refresh rate & .03ms response time)
  • Connected through a High-End Digital Port Cable to the Digital Port on the GPU)
  • SoundBlaster (X Soundbar) is connected via Fiberoptic connections
  • Using onboard integrated RJ45 Network port to a 2GB Internet compatible router connected to a 2gb Modem. (ISP Service / 2GBs service).
  • Elgato FaceCam Pro (4k) - USBC
  • Elgato StreemDeck XL, Elgato WAVE XLR + Mic) all connected via USBC.

All drivers for the GPU, Motherboard, CPU, Lian-Li Devices, and Keyboard, and Soundbar has been updated. No major software installed on the computer except for Autodesk Maya 2025 and Motion builder, and Unreal Engine 5.5x, Davinci Resolve 19.x, Visual Studio Code (Microsoft), OBS Studio.

I can run every application, visit every site, edit videos, and the unit does not skip a bit. It will not slow down, nor freeze, nor shutdown. If I run Unreal Engine 5.5x, the screen will black out when importing a cube, or move the sun light around. If I am luck, I may get a chance to add a brick texture before the screen goes dark.

I have checked to make sure that Unreal Engine is using the RTX GPU as any other device. I will not have any applications running. I even disabled Norton’s Anti-Virus.

I have tried the NVIDA driver for creators. Same result. I tried the driver for gaming, same result.
Please help.

I am a high school computer science teacher, and I am trying to introduce this application to my high school students by the start of the new semester which is next week. This isa new course that I am teaching, and I have 6 sessions of 30 students in each (180 students who all show up every day) when I was teaching Maya 2025 and Davinci Resolve).
