2. Move Qt5WebEngineCore.dll to the affected app’s directory

A major reason behind Qt5WebEngineCore.dll errors is that the DLL is not stored in the app’s directory but in another folder, where it’s accessible to a host of other applications.

In this case, simply moving a copy of the file from its initial location to the app’s dedicated folder (same as the app launcher) will quickly fix the DLL error. Also, if the DLL is missing, get it from another PC running the same iteration and architecture of the OS.
