Program Control Almost Unresponsive, Slow User Interface. Need help to clear or reset the list of files.

Hello.

When I try to customize My Norton Security firewall, the tab "Program Control" seems almost unresponsive.

I made a video so you can see for yourself. https://youtu.be/nn2oGSJ-Kj4

I got the "Advanced Program Control" OFF, so I can manage when a program tries to access the web. Then I'd decide to allow it or not.

I am a long time user of Norton Security, since NIS 2008 I Think...

After months using my new Norton Security Premium (current version v.22.8.1.14 over Windows 10 Pro) I realized I choose to block a program that now I wanted to allow access to the web. When I opened the Firewall and went to Program Control, I couldn't go through the list because the user interface was so slow.

I have lot and lots of programs listed in Program Control. I think more than 1000.

I would like to know:

1) Is there a fix for this?

2) Is there a way easier to clear/reset all programs listed in the Program Control tab? Where the settings are stored? I tried the Windows Registry and tried to locate some "ini"or "dat" file, but I couldn't find anything.

3) Of course I could remove and then reinstall Norton, but I'd like to avoid that...
