/hello, I cannot add games to my library

[Former user]

Hi. While attempting to add windows games downloaded through the "Twitch Desktop"application, I am prompted to add a title for whichever game I'm importing. When I enter the name, I'm prompted with this error window. Thanks for your work, and your time. Hope this helps, all the best!

Here's the error message:
