I can't upload image file.

According to the response message, "Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.impl.IOFileUploadException: Processing of multipart/form-data request failed. No space left on device".

Perhaps the server's temporary upload area has been exhausted?
I think it is the same reason why the project cannot be saved.
