In version 3 Collapsing Categories switched the plugin to the new gutenberg-based blocks instead of the classic widgets. Version 3 only works with themes which support gutenberg based widgets, which were released about two years ago.
I had the same problem, after install the old version everything worked again…

its bad!!!!!!!!!

I use simple widgets

After the update from version 2.2.7 to 3.0.8, all installed widgets disappeared and “Collapsing Categories” is no longer in the list of widgets!

WordPress 5.6.8
