Error 0xC00CE508 while loading package file into an XML document

I have a corrupted ssis package with this error:

Error: Error 0xC00CE508 while loading package file "H:\GBPL_NEW\Fact_Dimension_set_entries.caw" into an XML document. An invalid character was found in text content. Line 1, Column 3.

The caw file is present. Don't know where I am going wrong!!

I am also getting this while executing the package.
