Unreal Engine 5.7 Released

Until an official fix being provided, this command line fixed the rounded Background Blur not showing in the packaged build problem:

Background Blur Crash with 5.7 and Instanced Stereo

Hello! I ran into this as well: Kawase Dual filter post by ROJO (@ayoROJO) / X This is due to the DualKawaseFilter for slate blur added in 5.7. The implementor was a contractor and can’t fix it, but says he could report the issue. Try setting UI.SlatePostBlurUseDualKawaseFilter=0 to disable this new shader and it should fix your crash.
