The new Inking Brushes

Painter 2020
The Issue:
On a new clean layer, draw anything with any of the new Inking brushes. Do not use any other style brush on that layer. Just the Inking brushes only. Now right-click the layer and click Select  Layer Content. This will cause all layers in the project to become unusable.. You cannot draw on any of them. CTRL+D, CTRL+I, CTRL+ALT+H... nothing fixes it. You have to close out and open it again. There aren't even any ants.
