Choose File button Does Not Bring Up Dialog Box

[KeithWild]

I just updated my computer running Mojave to the latest Security and Safari updates. Ever since then when I am in the New Computer Package and click on Choose File I get no dialog box so I can't upload a package. I have noticed this same behavior for other websites also. I have no issues if I use Chrome so It appears to be something with Safari after the update.

Any ideas on what might be the issue?

I needed up resinstalling the OS from recovery (Command R) and this resolved whatever issue I was having with the Choose File not working.
