Lasso tool & Content aware fill problems with CC2019 Windows 10

If I select something with the lasso tool the marching ants do not appear, if I Ctrl+j the selected are jumps to a new layer but it remains invisible in the display. If I select something with the lasso then select another tool the marching ants appear.

The new content aware fill only becomes active if the marching ants are physically visible.

When launched the panel that fits in the middle of the content aware workspace will not load, giving an error.

After running the new content aware and return to the screen it does not appear to have done anything until a tool is clicked on in the toolbar and then the preview in the main window changes to show the results of the fill.
