System Information
Operating system: Windows-10-10.0.19041-SP0 64bits
Graphics card: NVIDIA GeForce RTX 2080/PCIe/SSE2 4.5.0 NVIDIA 516.94

Blender Version
Broken: version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560e7, type: release (Also on 3.1, 3.0 and 2.93)
Worked: none

Short description of error
Library weak reference seems to be set on appending, but are not pruned afterwards.
Similar to the task #94805
But instead of "Report Missing Files", one is using "Find Missing Files" instead.

This bug generates multiple "Could not Find '.blend' in"C:\etc"", after you have appended files to a new file, and the original file from which the files were appended cannot be found (was moved, deleted or is from a different computer)... one error for each file appended.

There exists projects where users must constantly append files from remote repositories, and that the user will NOT have access to the original blend files when trying to "Find missing files" that are completely unrelated to the appended ones to his project.
This error-spam in the popup window makes it very hard for the user to quickly and easily spot which important files are indeed missing, since there's a barrage of inocuous errors from files that were simply appended and therefore are not really "missing" anything.
Sometimes my entire window is covered with "Could not find 'file.blend" errors, and I have to check the info editor to find which files are indeed missing and which are just bogus errors from previously appended files.

There is no way to remove this "Library weak" information from the file within Blender, nor with Python , and it will always generate "Could not Find 'file.blend" errors.

Exact steps for others to reproduce the error

Open attached file and use "Find Missing Files" in any folder, or

Create a File1.blend with several default cubes..., save it, close it.
On another clean File2.blend, append all the default cubes from the previous File1 file.
Delete File1.blend (the one from where you appended)
On File2, use the option "Find Missing Files" (File → External Data → Find Missing Files) on any folder
The error 'Could not find 'File1.blend'" will appear, one error for each default cube that you appended.
