UE4 Always crashes when opening file explorer from the editor

Can I ask, for those of you where its crashing, are you using the Launcher Version or Source Built Version of Unreal. I’m finding every version of UE or project I open from the Launcher crashes about 5 seconds after a windows explorer window opens - select build location, export asset location, doesn’t matter. However the same UE version 4.26.2 I’ve compiled from source does not exhibit this behavior.
