WORKFLOW SHOWING ERROR LOG AFTER RENAMING IT

Dear Team,

How do i recover a Knime workflow with the error log below :

“java.io.ioexception: unable to parse xml: line=2: content is not allowed in prolog. xml: uri=java.io.bufferedinputstream@44308cf4 dtd: uri=null”

I renamed the workflow and couldn’t open it anymore, what might have gone wrong and how can I retrieve the workflow.

I wouldn’t mind sharing my screen if that would help.

many thanks
