Mask panel intermittently disappears in v11.4.1
Lightroom Classic 11.4.1 on MacOS (Apple Silicon) with Studio Display. Lightroom is in a single window sized to the full screen, but not in full-screen mode.
On many occasions I have found that when I click on the masks button (small round circle) the panel below expands to show the effect parameters, but the panel to the left which has the masks in it does NOT appear. It is not minimised down to a small box, it is missing entirely.
It can be made to appear by click on the green dot at top left to go to full-screen mode (and then back again) or by quitting and reopening Lightroom.
Others have reported variations of this problem and it has incorrectly been marked as a user error or fixed. It is an expected behaviour of the application and is disruptive to workflow.
