Posted by developer: This issue applies to the legacy MySQL Workbench 8.x implementation that is no longer supported or maintained. MySQL Workbench 26.7 is a complete rewrite using a new technology stack and does not use the affected legacy implementation. Therefore, this issue is not applicable to the current MySQL Workbench product and as such is closed.
Description: I opened MySQL Workbench and made a connection, as soon as I open the already established connection, I see this error- {MySQL Workbench Unexpected Error MySQL Workbench has encountered a problem Parameter is not valid. We are sorry for the inconvenience but an unexpected exception has been raised by one of the MySQL Workbench modules. In order to fix this issue we would kindly ask you to file a bug report.

Thanks a lot for taking the time to help us improve MySQL Workbench! The MySQL Workbench Team} How to repeat: No idea. Suggested fix: I tried to go to MySQL workbench App Data through C drive and tried to rename the folder after saving or backing up the connections.xml file somewhere but I am unable to debug or resolve the issue. I am unable to open the established connection or go into the DB.
