Summary

Whenever I try to open a previously created and published map, the UEFN crashes with ‘GPU Crash dump Triggered’ error.
This has not occured prior to the latest 32.00 UEFN update and causes me to not update/make changes to my existing project.
My PC specs are above average (32GB RAM, AMD Ryzen 7 5800X3D Processor, NVIDIA GeForce RTX 4070 GPU).

Any help is highly appreciated

We are working on some issues today, this should resolve itself once we have a fix live. I’ll check back.

Same here, but only with larger projects. Simpler projects open properly without any issues.

Hello! I think the problem might be caused by the latest update (the same one that crashed the creators’ portal yesterday)

I had the same issue as you but I managed to solve it by opening another unreal project linked to the revision control and afterwards opening the one crashing

This was using File: new/open project, with the functional project open

I hope it is useful to you, good luck!

Me too.

Not working for me.

I found a possible temporary solution. First, create a new, empty island and open it to configure the visualization platform. I noticed that the problem occurs when this function is disabled.

To fix it, go to the top right corner and click on “Settings,” then “Visualization Platform.” Next, select “PC” and choose the option that best suits your computer. I activated “PC D3D SM5.” After doing this, try opening the project that was crashing again. I believe this will work!
