My Lightroom app keeps crashing. This started a couple nights ago. I was trying to use lens blur and it was saying they encountered and and issue and needed to close and prompting me to send an error report. I stopped trying that and just kept working then suddenly it closed with no warning. After that I tried probably hundreds of times and sometimes it would close immediately while other times it would let me navigate to a date & image and then close. The next morning it worked fine for 2 days and then tonight the same issue has started.
