This looks like a GPU crash @Horrid please make sure you don’t have RivaTuner or MSI Afterburner running in the background and also make sure your drivers are up to date. Thanks! ---

Hey im getting the same crash when i try to run it and stream it but i all so looked. It is maxing out my 2 3090. That will cause it to crash so make sure your video card is not maxed out if so lower the setting in unreal till you run about 70 % on your video card you need any more help fell free to hit me back. ---

the solution for me was a complete clean reinstall of my graphics card using DDU i unfortunately don’t have the best pc… running a 2070 super… but it works the only caviat is whenever there’s an update to Fortnite and uefn i have to redo the clean reinstall or else uefn crashes again … example: ran fine until 2 days ago when a new update came out everything crashed again did the DDU clean wipe again and now it works again… epic really needs to sort this out needing to clean install the driver every update is a critical issue. ---
