You can’t back save to older version. Your best bet is to export as IFC … when you link that into 2024 it will generate a .ifc.rvt  file which you can use.

do u have all the updates installed… maybe u can try fix the crashing issue . Check your other post and upload the Journals (See Link Below)

What is causing the crashes?

Do you get any messages as it is crashing?

Does it happen in all files?

Reinstalling Revit may fixe the crashes.

If not, maybe there is something wrong with the model.

You should resolve the crashing issues. Did you install the latest SP? R2025.4?
