Unable to save anything!

Hello! I have encountered a severe error using 3dexperience.
It is simply not able to save anything. I have gotten a host of
different errors in addition to the ones I have attached. I can edit
but not save. The error where someone else has modified the document
is false, as it has happened multiple times, and I know for a fact
that noone but me has been working on the component.

The errors I get generally seem to indicate that there is some sort of
server error
