Excel AddIn doesn't work any more - used to worked properly.

I have made a C# VSTO Excel AddIn code(several thousands lines) that have been worked perfectly for years.

I'm with Office2013(32bit), VisualStudio2017 and Windows10.

...

This problem started with Windows update "KB5050188", I guess.

The AddIn started well with Excel but something keeps it working(Pls see attached screenshot).

It remains Unchecked always in this pop up.

I cannot make it Checked(Checked it, but it doesn't have its own effects).

It doesn't have any Ribbon tab in Excel main UI also of course.

..

So, Today morning, I have tried with Office2019(32bit) and VisualStudio2022 but, it make the same result.

...

What do I have to do ?

I think, I'm missing some kind of "security option" etc.

If I block WidnowUpdates(actually, all of the WindowUpdates, because The specific update is invincible, I cannot pinpoint-block it), then Excel AddIn apppears and works properly.
