I just upgraded to Lightroom 5.5. Upon opening my catalog I find that I'm unable to crop pictures. As soon as I select the tool the image disappears and the only way to get it back is to go to the Library Module and select picture again. Image also disappears if I go to History and select an earlier point in the edits. I have made no other changes other than the upgrade. I tried increasing my cache to 20 GB from 2 GB to no avail. Help.
So no help. I tried uninstalling 5.5 and reinstalling to no avail. But uninstalling 5.5 and reinstalling 5.4 fixed everything. I believe there are numerous problems with 5.5 judging from the wide variety of errors.
