Failed to save target content: Name cannot begin with the "

Question

I have a Freelance 2018 Trados Studio version. 
 
 Upon completion of my translation, I tried to save it as a word document using the option "save target as". 
 
 I received the following erro message: Failed to save target content: Name cannot begin with the "<" character, hexadecimal value 0x3C. Line 2, position 3226. 
 
 Solutions presented in this platform for similar problems (eg https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0036304 ) were not helpful as I cannot just open the .sdlxliff file. and search for the string "<" to delete it as this is not a string and I find myself with dozens of "<" characters. 
 
 The source document is a PDF document, could that be part of the problem? 
 
 Thank you,
