3dmax can't open my files

Can anyone help me with this…
My files cannot be opened in 3ds Max. I exported my SketchUp files to FBX, but these were corrupted when they tried to open them. Later, I saved them as OBJ files, but they also couldn’t open those. Now they are asking if I can save the files in an older SketchUp version, but the 2024 version doesn’t have this option. What can I do to export the files so they can open them in 3ds Max in China?
