Indesign file opens but stays in background and apple finder comes to the foreground and doc opens up.

This is an odd one, I double click on an indesign file, indesign and the file opens up but indesign goes to the background on my Mac, and the finder to the foreground then the Mac doc appears and stays there, I have to then click on the indesign layout to bring it to the front, the doc still stays until I click on something else on the doc then it disappears. This started when an agency sent me a brochure to work on and now it is happening with every file I open. I have searched and not found anyone with the same problem. So far I have deleted the Indesign preferences and that didn't fix it, then updated to the latest indesign and that didn't work either. Both illustrator and photoshop are working great. I would be grateful for any advice. Thank you. My set up is: Mac Studio 2023, 64GB ram, Sequoia 15.7.1, Indesign 2026.
