can't save level and assets anymore

Hello,
I have a level that loads without any issues, but it gets stuck at 0% when saving.
It is an archviz level built from the VR template. Nothing special or specific. Other levels from the project can be saved without any problems. Assets can be saved as well.
Does anyone know how to help me?
UE 5.3.2.
