Hello Heinz Schweitzer,

Thank you for the bug report.
To investigate further this issue at our end, may I kindly request you to launch workbench under debug mode (--log-level=debug3) and provide unaltered workbench log file(more details about log are explained here - https://dev.mysql.com/doc/workbench/en/workbench-reporting-bugs.html)?

Regards,
Ashwini Patil

No feedback was provided for this bug for over a month, so it is
being suspended automatically. If you are able to provide the
information that was originally requested, please do so and change
the status of the bug back to "Open".

This is still occurring in v8.0.42.

I am connecting to a MySQL Enterprise - Cloud 8.4.0-u7-cloud server.

The crash only occurs if I use the Database -> Connect to Database… option.
Connecting via the saved connection tile in the main screen works fine.

Log attached using --log-level=debug3
