Hi
In your scenario, how did you connect to MySQL, via "MySQL Database" data source type in desktop? Based on my research about the error message "A call to SSPI failed, see inner exception", it seems the issue can be caused by the windows update, see: A call to SSPI failed, see inner exception - The Local Security Authority cannot be contacted.
Also please verify you are using correct server and database name, and authentication, credential when connecting to MySQL database. Please use the latest desktop version 2.38.4491.282. And enable desktop trace log to see if you can find useful information.
Best Regards,
