Quick follow up for anyone else who gets here from the same error: there’s a workaround by @ApellusMagnus on a duplicate ticket for this issue:
The workaround is incredibly simple: change line 16 of Engine/Source/ThirdParty/CEF3/CEF3.build.cs to
bool bUseExperimentalVersion = false;
This resolved the issue for me.
In my case, I’m lucky that I can rebuild the editor source with this workaround. Not sure if there’s a way to achieve it if you’ve only downloaded the prebuilt binary.
