Can't open my project from the Epic Games Launcher

Hello! Brand new UE user, on a brand new PC.

I can’t open my project from the Epic Games Library launcher. I get an error message saying I need to create a default program for the file. Windows 10 has default app settings, and I don’t see a way to add an UE4 app or find an association with a .uproject file.

I am able to open my project by launching the UE editor, but for some reason it doesn’t work from the launcher.

Any ideas how to fix? Thanks!
