Control rig

I want to change a few animations and I finally got to install the Control rig - however it looks like this is no longer working correctly in 4.24? I can create a control rig, but I am not able to get the animation tab (shift+6) to work!

I got a version 4.23 running also, and for this the animation tab , but I am in doubt if this will work in future versions?

In general I also wonder if this can be used to make/fix animations, that can then be used without the specific BP features - are the animation made with ‘control rig’ dependent on the control rig assets?
