Saving Error on 3D Experience

One of our member have problem saving changes to 3D Experience in a large assembly. This is what he said

"For more context, it started happening after i did a batch save to 3Dexp in which it failed and then I was stuck in asynchronous save, so I reinstalled 3Dexp

I tried saving a single part and it worked, but for larger assembly not working which is odd" 

Doese anyone know how to resolve that?
