Solo Feature Stoped Working!

Since the latest updates a lot of things have gone terribly wrong in Rive, such as components or elements are not clickable anymore from the artboard, you can only select them from the left panel which is very counter intuitive when you have your eyes fixed to your design but the most important thing Solos have stoped working.

I have tried to create a Solo group using hotkeys (CMD+L, CMD+S), I have tried to toggle it from above in the Artboard Menu section, I just simply cannot create a Solo anymore and I'm sure I am not missing something.

I have a lot of projects working with that feature and on those projects the Solo Function is still available because it was created before the updates, but I cannot add new ones!

Please Help!
