You have Windows-PC ?
The "Assertion Failed" error is caused by Windows problems.
The "Libraries" that appear in File Explorer (Music, Pictures, Videos, ) are just links to the physical location of the folders.
eg. "Music" = C:\My Documents\Music
If you have moved the location of your pictures folder (or My Documents) then the Windows link "Pictures" does not know where the physical folder exists- and the error occurs.
Read similar explanation in the paragraph - "Additional Information" at this link:
I have found that it is best to never use the "Library" links in File Explorer for anything you do in Lightroom.

Sorry, you're having trouble using our Product.
May I know where your current catalog and its backup are located?
Are the originals saved on your external drive?
Thank you so much, wobertc and Akash Sharma, for your attempts of help me.
yes, i use windows 7 ultimate, there have been no changes in any unit or folder, all are intern units, but the only thing I have done is erase (After I have done the catalog backup) the content of lightroom folder in c:users/user/pictures/lightroom (in spanish version of my windows 7 ultimate "Mis imágenes/lightroom") for the reason that lightroom completely filled hard drive c: with almost 60 gb of data, Then I detected that deleting the contents of this lightroom folder in c:users/user/pictures/lightroom (or in my case "Mis imágenes/lightroom" folder) is that windows 7 has changed the name of the folder "Mis imágenes" (in spanish) by pictures (in english), but I have also tried to change it to original name by windows registry metod searched in internet with several attempts and has not been fixed.
But I do not understand this:
1. Why did another previous catalog version work perfectly? (Should have the same problem)
2. If i have a catalog backup in another disk unit, physical or not, why this backup depends on the c:users/user/pictures/lightroom folder if this folder maybe, deleted, empty or not useful?
To Akash Sharma:
Everything is on internal hard drives, no changes at this, units or folders, was to make the copy of the catalog and soon try to load it, although as I said before I deleted the contents of the lightroom folder in users/user/pictures/lightroom
By the way the program also hangs when trying to open this catalog
I will continue trying to fix the problem, We will see if it can be is in the name of the folder c:users/user/pictures/lightroom
Any other suggestions?
Thank you very much.
Well, i I already tried to follow this tutorial step by step with perfection with no results, https://helpx.adobe.com/lightroom/kb/lightroom-error-assertion-failed-update.html
I do not understand what it can be, virtual names of pictures folder in "c:/users/my user name" can cause the problem but between lightroom and windows do not seems to be clear, i have this content in windows registry "%USERPROFILE%\Pictures", Even I have created a folder "pictures" following the tutorial in "c:user/my user name" ("Mis imágenes" folder already existed) restart windows, i try to rename this virtual folder or folder with the name of "Pictures", later with name "Mis imágenes" or too "Imágenes", but all it's useless, same message and program lock again and again, "assertion failed"...I have too tried thousands of other things, among other, uninstall and install the program, for example, but nothing...
Is it possible that the catalog file is corrupted or damaged? Is there any way to check it?
I'm desperate and tired....
It may be time to contact Adobe support and see if they can help.
Also, can you post screen-clips of File Explorer expanded folders- Pictures, Lightroom, and the folder with your image files? These may give us more clues.
It is a bug or file corrupt of the catalog backup, now I am certain because I have restored a backup of windows 7 that was a few months ago and neither this catalog works, pictures folders and folders routes was correct and had not been touched and nothing had been erased, other previous catalog backups work fine, so I've come to the conclusion that the catalog file is corrupted.
Is likely to contact me directly adobe although I have all my hopes already lost, for the moment, and if a miracle does not happen, my work for months has been lost due to a bug, failure, in the backups of the catalogs, the copy method should have more security but it's not like that. In spite of everything I am very grateful to adobe for his magnificent programs.
Thank you very much
