Unreal 5.1.1 and 5.0.3 crashing

My editor crashes every time I open it even with a completely fresh install and blank project. I am using the default settings and the third person template. It typically crashes if I go into the blueprint editor, but I also have had a crash just panning around in a blank project. I have never had an issue before and have ran some pretty heavy scenes before. I have an RTX 2080 Max Q.

I also have my crash log.

Hey @brendancasimir!

Would you mind sharing that crash log so we can get a better idea of what may be going wrong? In the meantime, I would double check that all your drivers are up to date.

Any additional specifics you can provide may go a long way in solving your problem!

@Quetzalcodename i am sorry for not providing it before. I have just edited the post to include the attachments. thanks!

this is the report i receive when it crashes

Located your Nvidia shader cache in the app data folder and delete it / delete temp folder / delete your save and intermediate folder in the unreal project, see if it works > run repair on from the launcher on both versions. Sounds like you got a bad shader compile.

thanks,

I don’t know if this was the issue or not but I reset my nvidia 3d settings. it seems like it wasn’t utilizing the graphics card properly.

Hey @brendancasimir!

From your crash log you are correct, as the following usually indicates an issue with your Nvidia drivers or settings.

Is everything up and running for you?

Disable Nanite in the entire project and see if it fixes it - You could have a bad asset that will continuously crash nanite.

UPDATE : I can create this issue - just accidentally set an object like a sphere to use Nanite and use it in BP where it is has a transparent material on it. BOOM the editor will die every time. You have to disable Nanite at the project level to get the BP to open again with out crashing then reset all object to NOT use nanite that could be using a transparent material then you should be running again.

Did you fix the problem? I’m leaving this comment for others who are stuck in this issue.

I changed the configuration in NVIDIA Control Panel and solved it.
Go NVIDIA Control Panel > Manage 3D settings > Global Settings, and change Global presets into Base profile. In Base profile, go CUDA - GPUs to All. It worked for me.
I guess this issue is related to nvidia cuda setting.
