Thanks for reporting this issue.
1) We are able to see the problem with XlsIO and DocIO and will have a fix available as soon as possible.
2) In the meantime, please make the following changes to pass certification for other controls
Run Notepad in administrator mode and open this file
C:\Program Files (x86)\Syncfusion\Essential Studio\10.3.0.64\SDK\SDKManifest.xml
Delete entries for DocIO and XlsIO
Save and close the file
3) Open this folder, copy the XlsIO dll and DocIO dll to some other location for backup and delete them from here
C:\Program Files (x86)\Syncfusion\Essential Studio\10.3.0.64\SDK\References\CommonConfiguration\neutral
Now, clean the solution and rebuild it. It should pass certification now.
Please let us know if you still have any problems. Sorry for the inconvenience.
