Description:
I encountered an unexpected error while using MySQL Workbench. Upon launching the application, a pop-up message appeared stating:
"MySQL Workbench has encountered a problem. Parameter is not valid."

This error prevents me from proceeding further with my work. The issue persists even after restarting MySQL Workbench and my system.

Steps to Reproduce the Issue:

Open MySQL Workbench.

Attempt to connect to an existing MySQL instance.

The error message appears, blocking further interaction with the application.

System Information:

Operating System: Windows 11

MySQL Workbench Version: (Provide the version you are using)

MySQL Server Version: (If applicable, mention your MySQL server version)

Troubleshooting Steps Taken:
✔ Restarted MySQL Workbench.
✔ Ran MySQL Workbench as Administrator.
✔ Restarted the MySQL Service.
✔ Cleared MySQL Workbench Cache (AppData\Roaming\MySQL\Workbench).
✔ Checked for MySQL Workbench updates.
✔ Reinstalled MySQL Workbench (issue persists).

How to repeat:
Expected Behavior:
MySQL Workbench should open and allow me to interact with my database connections without errors.

Actual Behavior:
The application displays the "Parameter is not valid." error and prevents further usage.

Additional Notes:

No recent changes were made to my MySQL installation.

The issue started appearing suddenly without any modifications to system settings.

Suggested fix:
Restarted MySQL Workbench.
✔ Ran MySQL Workbench as Administrator.
✔ Restarted the MySQL Service.
✔ Cleared MySQL Workbench Cache (AppData\Roaming\MySQL\Workbench).
✔ Checked for MySQL Workbench updates.
