Sketchup texture loss

Copy the d5 folder with the edited d5 file to another computer with the sketchup file, and then open the d5 and sketchup files on that computer, where d5 displays the material, lights, and so on that computer.However, when I click “associate” in the sketchup, the correct material just displayed in d5 will be replaced by the material in the sketchup.

And I’ve found that these missing materials have some characteristics:

These materials are added to the d5 material library.(After creating a new blank material in sketchup, replace it with the material in the d5 material library)
In the above materials, there was originally a map in the sketchup, but then the material replaced by the d5 material in the d5 material library will not disappear.The blank material without mapping in the sketchup, even if the material in the D5 material library is added to the sketchup, it disappears and becomes the blank material in the sketchup again.
This is a serious problem that causes my files to be edited only on one computer.This is very inconvenient in teamwork. Please solve it. Thank you.

Hi! Sorry for my late reply. Have you changed the version of SU since you changed your device? If you have different versions of SU on your two devices, note that Livesync does not work with versions of SU below 2020, and mixing realtime and non-realtime plugins will result in the material resetting to the original material.
