Description:
When launching Workbench, an error pops up that says "An Error occured while loading image search_sidebar.png"
After closing that error message, Workbench will load. When attempting to connect to any connection, another error message pops up stating: 
"MySQL Workbench has encountered a problem
 Parameter is not valid."
Once you close that message, Workbench will crash.

How to repeat:
Launch Workbench, connect to a server, and close error message

I'm having the same issue.  Is there a fix yet?

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.
