My version keepscrashing, too. Everytime I try to use a brush, a linear mask and so on, it crashes. My PC works on Windows 11 (all updates installed), Processr i7 13700K, installed RAM 64 GB, NVidia RTX 3060, last update was yesterday. Only the very basic functions can be used, including noise reduction. But any function using masks crashes instantly. No report is sent to Adobe, but to Windows.
Thanks for investigating. But I don't know if you will find anything usable in the crash bucket, as LR doesn't terminate the process itself. It only freezes, simulating that it is loading something. I made a new test just now - after waiting 7 minutes for LR to react after clicking on sky selection I tried to shut the program but as always, the screen went almost white with only a very faint image coming through the white haze. Nothing more happened, only the Windows dialogue opened asking whether I wanted Windows to shut down the process or if I preferred to wait for the software to react. I preferred Windows to shut it. By the way, I suppose I reported my problem in the false thread because I hadn't noticed that this is a Mac thread. I use Windows, as I explained in my text above. Sorry for that.
Yesterday's update to LR 13.01 has resolved the reported problems. But now I don't find the search bar in the Library Module, it seems to have vanished for good.
How exactly did you reinstall? I reinstalled Lightroom, reinsalled Adobe CC, event reinstalled the whole macOS and nothing solved the problem. I have jobs I need to edit..
