If that is your scenario? If not, please share with me the detailed steps about how do you reproduce this issue.
If it is your scenario, to check if this issue is file related, please create a new workbook to check if your user can rename the embedded pdf file normally. If this issue happens to all workbook, please try another pdf file to check if it is pdf file related.
Besides, please also share with me a copy of issue related workbook and pdf file to let me have a better understanding of your scenario. To protect your privacy, please share with me your file via Private Message.
