Error Message ("Attempted to read or write protected memory") trying to start translating a Word document in Trados (2017)

Hi,

I have been working with Trados (2017) until yesterday with no issue.
Today, I needed to start a new translation but received the following error message when I tried to drag and drop my file (or browse for it):
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
I have done what is advised on https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0030771 and https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0028590 to no avail.

Would you know the cause of the issue and what to do to resolve it?

Any help would be greatly appreciated!

Many thanks,
Claire
