every time i reach the "Bulk data transfer" step in the migration wizard process, MySQL Workbench stops working showing a "Not responding" message on the main window bar and a failed icon on the "Copying data to target RDBMS" step then the whole window turns plain white, and 2min later it turn plain black, i can't click on anything in the software before this happens to try to retrieve logs or anything because the software is frozen. Only thing i can do is kill the task in Task Manager and if i open the software again i have to repeat the whole migration process to reach this point again and get bugged.

I am migrating from SQL Server Management, all the previous steps were done correctly and successfully along with the connections.

How to repeat:
just startup the migration wizard from database tab in MySQL Workbench and do the process to migrate from SQL Server Management.

Hello Michel Asmar,

Are you using SSH to connect to source or target RDBMS?
Also, 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). Thanks.

Hello Michel Asmar,

Thank you for the feedback.
I tried to reproduce your issue on windows 10 with workbench 8.0.25 but I am not seeing any issues at my end.
