"Unable to complete action Errors occurred while trying to load the workbook "/mydirectory/file.twbx". The load was not able to complete successfully. Error Code: 446A2EC6"

Hello, I'm getting this error when opening a particular file. I'm using the newest versions of both Tableau Desktop and Server. Recently, there was an upgrade on the newest version of Tableau Server and since then data extracts for this report failed to refresh. Therefore, I suspect there might be an issue with this yet I have no idea how to resolve it.

Many thanks!
