Mask is not responding on Lightroom Classic 11

[Leo6C14]

After I create a new mask filter, i can't edit/resize/move the created mask (same behavior for Radial, Linear and etc.).

I am using M1 Macbook air, macOS Monterey (v 12.0.1), Lightroom Classic 11

Are you using Loupedeck by any chance? If so, check with them for an update.

Thanks for your reply. I am not using Loupedeck. 

I also notice all options for mask got grey out. It is very strange behavior.

I also see some weird stuff !  EDITED-  My stupidity!

I created a radial mask, done.  When I return to the radial mask by selecting the square icon for the mask I cannot get the 'bounding' outline visible again for the gradient.  I can move, resize, rotate with the mouse cursor in a suitable place but the guidelines are not visible.-

My screenclip- The radial gradient fully adjustable, but guidelines not visible.

In the screenshot posted by Rob_Cullen, I get the impression that the mask group is selected, not the actual mask, click on the mask group to expand out the mask and components, select the mask.

In your video, I get the impression that your mask pin is not selected, did you try clicking on the pin.

Thanks for your reply. I did select the pin but it is not responsing to any of my changes.

I also notice all options for mask got grey out. It is very strange behavior.

Duhhhh! Slap me silly-  Press keyboard [H] and the guidelines re-appear!!
