Find Element - Default vs UIA

Hey,

One of my team members has developed a UiPath process that leverages off the “Default” UI Framework when using “Find Element”. However, when running this on another PC, it does not appear to pick up elements on screen unless we switch to the “UIA” UI Framework. The PC models and UiPath versions are the same so curious as to why we need to make this tactical workaround? Any ideas?

Thanks!
