Version of Adobe InDesign, InCopy or InDesign Server: 21.0.2, updated 12.01.2025
Steps to reproduce the issues: There are multiple issues occurring.
1. Open existing file, last saved on 11.03.2025.
2. App freezes when trying to use any function, e.g. copy/paste, duplicate page. Takes up a few minutes for any function to complete.
3. When trying to save the file, I have to save as a new file.
4. When exporting to PDF, does not Use InDesign Document Name as the Output File Name despite being selected. If selecting Range, only allows All Pages in dropdown. Does not export accessibility tags despite having both Create Tagged PDF and Use Structure for Tab Order are selected.

Expected result: for the file to use the document name as the PDF file name, for it to be able to export only a range, and to have accessibility tags preserved in PDF.

Actual result:
1. Freeze and lag with each step of the process.
2. File will not export to PDF. Sometimes getting a Failure pop up but cannot identify any issue.
3. Have to choose option to open file with, but it does not save the file in the location I selected. I have to resave it in order to run Accessibility Checker.
4. No tags export with file even though everything is properly mapped in InDesign and exports made 11.3.25 retained the tags.
