Backup not finishing. No .tly file being created.

So I have seen multiple posts about backups not creating the .tly file and the comments have been that "your backup didn't complete", which really isn't helpful.  I dug and dug and finally found mention of an application error in my Windows Event Log.  Can anyone tell me what this error means and how I stop it so my backup can complete?  The attached file is a screen capture of the error log.  This is on an older Dell Inspirion running Windows 10 Home.

Sorry, this is Elements 10.  I'm trying to create a backup to migrate my catalog to Elements 2021 on a new machine.
