2.3.3 Effect->Equalize Gone, Can't Enable?

I just upgraded to 2.3.3 and recorded a podcast. I use the techniques described in the thread on this forum for audiobook mastering, where the first step is Effect->Equalize. I didn’t see Equalize in the Effect menu, so I went to Effect->Add/Remove Plugins and saw it there as disabled. Every time I enable it, it disables again and never shows up in the Effect menu. Any help? Thanks!

It has been replaced with the “Filter Curve” effect: https://manual.audacityteam.org/man/filter_curve.html

So previously I used the below Equalization settings. How would I do this with the Filter Curve?

Effect > Equalization > Select Curve: Low rolloff for speech, Length of Filter: about 5000 > OK

In the “Filter Curve” effect, click the “Manage” button,
then in the “Factory presets”, select “Low rolloff for speech”.
