New To Unreal Engine - Loaded "Puzzle" Template - Crash When Pressing "Launch"?(Windows 10)

Hi,

We are new to Unreal Engine.
We are using UE version 4.25.1 on Windows 10 Pro 64Bit version 2004.
We started UE and loaded the “Puzzle” template tutorial.
If we click on “Launch”, UE freezes and must be ended in Windows Task Manager?
Any ideas what we are doing wrong?
Thanks!
