As this has happened to me over a dozen times in the past few weeeks, and after each instance the dialog box appears stating there is no known solution so would I like to sned in a report, I am hoping it is not breaking news. But, when I attempt to go to the Maps mode from Library or Develop after having selected a few (or a few dozen) images, LRC unexpectantly quits.
Through trial and error, I have found that if I do not make an image selection and then go to Maps mode, it usually does not just quit - so there is that. But obviously not what was intended, since this is new behavior since gettting the latest update of LRC.
If it is pertinant, I am runing this on an M1 MacBook Pro with 16GB of RAM (and an external 2TB SSD) on OSX 11.5.1
