I have been using Lightroom 6 on Windows almost since it was released without any problem, but since last week (at least, I haven't used Lightroom for the past three months), it closes without any warning while I'm using it. I noticed it happens every time I press O for face recognition or when I want to add a tag manually on a person. But it also happened once while I tried to delete a folder. I solved this first problem by deleting the pictures inside the folder first, but for face recognition I can't find a way to bypass the software closing.
Does anyone have an idea where the problem comes from and/or how to solve it?
