Hi, I am having this awful issue couple of months. I named unfortunately one catalog with ending three dots fastly...
After that Lightroom crashes and informs that: Assertion Failed!
What can I do to get my Lightroom working again? This is definitely some bug or something.
What can I do? The Uninstall and install did not work.
Have you tried renaming the catalog back to what it was before?
If you do a forum search for "assertion failed", there are plenty of matches, most of them point to this document:
I tried that first without success. Deleted the catalog, but even renaiming gain no success.
But, i did managed to reinstall the program without the previous remembered assets, so that's was the only thing.
I believe, that there is issue when naming the catalog end with tree dots...
I am not naming anymore the catalog end with three dots (...) .
Yes, the three dots was a very bad idea. Any dots at all. Using any other special character used by the file system is bad, too.
