Trying to change the scalability of the editor makes unreal freeze and then crash

Trying to change the scalability of the editor causes unreal to freeze and then crash.

I’ve tried reinstalling unreal and it happens even in templates.

The first time you do this in a project, UE will hang for a long time while it recompiles basically all the shaders in your project.

You won’t get the shaders compiling message for quite a while. It’s possible if you have a large project, or a slightly older PC, that it can’t cope with this.

Once you have recompiled the universe, you can switch back and forth between different scalability settings.

If you don’t want to wait until the end of time, an alternative is packaging your project for distribution. Then, you don’t have to wait at all when you change scalability. The only downside is you have to write the changing of the settings into code somehow. A widget that calls ‘execute console command’ would be good.

here is how I fixed:

go here

C:\Users"your username"\AppData\Local\UnrealEngine\Common\DerivedDataCache

delete everything inside this folder

Your project will take some time to open, but all the corrupted files will be gone
