That is for removing the empty customization files.
This actions emerge from the though that there may be some corrupted Personalizations due to empty customization files.

Work with your developers for the personalization and customization related things.

Normally, I would suggest the following for this case ->

 How to deploy customizations that are created in the package oracle.apps.xxprod.* rather than xxprod.oracle.apps.* or xxprod.oracle.apps.xxprod.* on EBS 12.2.X? (Doc ID 1609939.1)

But! you say the issue appears only for some users and that makes me think that there is some things which get corrupted for the user level.. personalization-customization and all that..

If this issue is related with a pure custom page, then review your code.. (these errors for standard pages are either solved with those personalization/customization moves or with the patches that change the standard classes.. So , if this issue is related with a pure custom case, then work on the code. .

--again, it only appears for some uses and that what makes the issue complicated..
We need to go one by one.. So  for now,  just consider the actions that I provided you in my previous updates and eliminate the action plans one by one till you get the correct action plan..

As for those customization related actions, work with your developers and test it on your TEST instance before doing anyting on PROD.. You may considering taking a backup in certain level before taking any actions on PROD.
