Description:
I tried to start-up MySQL server through MySQL workbench and it failed with this error:

Unhandled exception: Wrong number or type of arguments for overloaded function 'TextBox_append_text_with_encoding'.
  Possible C/C++ prototypes are:
    mforms::TextBox::append_text_with_encoding(std::string const &,std::string const &,bool)
    mforms::TextBox::append_text_with_encoding(std::string const &,std::string const &)

Here is the start up log:
2020-06-23 01:31:17 - Starting server...
2020-06-23 01:31:17 - Executing 'launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist'

My versions:
MySQL workbench: 8.0.11
MySQL: 8.0.20

How to repeat:

Hello Neil Zhang,

Thank you for the bug report.
Please note that we don't fix bugs in old versions, don't back-port bug fixes, so you need to check with latest WB version. So, please, upgrade WB to 8.0.21 and inform us if problem still exists.
Also, looking at the supported platforms list we are no longer supporting < MacOS 10.15 versions and same can be confirmed from the "Supported Platforms: MySQL Workbench" i.e https://www.mysql.com/support/supportedplatforms/workbench.html

Regards,
Ashwini Patil
