From what I understand you're having an issue where you can't start the desktop app on your recently updated Windows 10 device - correct me if I'm wrong please.
In order for me to investigate, I'll need to get and analyze the full error log that corresponds to the error message pop-up you're getting - if you're not getting any at all do let me know please.
You can obtain the full text of the error by clicking on the blue link within the error message pop-up. This will open a file with the full text of the error. Please copy and paste the text in your next response here.
Thanks a lot and I look forward to your answer with the error log.
