Citra qt for canary vanished when i restarted my laptop

And now when i try to reinstall it, it gives this error:

note: it was working perfectly till yesterday, today when i tried booting it it said the location has changed, and when i went to the folder only citra-qt was missing. i deleted the folder and tried reinstalling it but this error

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.
