"Lights Out" problem

Lights Out stops working for some reason. I click through on L and the info appears every third click but everything else stays the same - gray w/menu bar showing etc. If I go into Preferences and change Lights Out from black to dark gray and then back to black, it starts working again, for a while - but then it craps out again, and I'm getting tired of having to do that over and over again. I used Lights Out constantly for years in LR5 without any problems. Any suggestions? 2019 16-inch MacBook Pro, 10.15.1
