I almost cannot use LR after update from 5.4 to 5.5. It gives me this error:
This error can occur when you've been using Lightroom for a while without restarting, especially have been if you've been using many menus. One way that you can use many menus is if you have a large number of Develop presets and you have been right-clicking on your photos to perform menu items. "
This problem was non existent in previous versions and I had them all from 5.0 to 5.4. I do have a large develop presets, but that was not a problem before. Also I am not working in the Develop module. I am in grid view and applying a preset from the Quick Develop drop-down menu.
Any help would be appreciated.
Your issue has been acknowledged by Adobe. They provided a temporary, incomplete fix in LR 5.5, and they plan to provide a more complete fix in a future update. See this thread for more details:
If you have more to add, you might add it to that thread, where Adobe is more likely to read it.
