Description:
When loading up mysql workbench - there is initially an error saying the sidebar image cannot be loaded.

After the application loads - when double clicking a saved connection that did previously work (and entering the password when prompted) - it pops up the 'Opening SQL Editor - please stand by...' window before displaying a new pop-up:

"Parameter is not valid." and the application stops responding when closing the error pop-up message. I've tried several connections they previously worked - and also new connections.

The sidebar on the right is also greyed out and has the same: "Parameter is not valid." error when interacting with the greyed out icons

How to repeat:
Open MySQL workbench (to get the first error message)
create a new connection and enter password (to get the second message)
