Thank you for the bug report.

- Launch WorkBench 6.3.6 on Windows 10 Pro
- From Menu Database->Migration Wizard
- Click start Migration
- Selected Source RDBMS Connection->Database System Mysql->Standard TCP Localhost
- Target another MySQL instance on localhost
- Processed all steps of migration
- Database->Migration Wizard isn't more works.
- Close WorkBench and launching it again Migration Wizard works.

I have the same problem and I reported it back in November. Only one response from the MySql Development Team that said I can only have one instance of the Workbench running at one time. That wasn't the issue. I have only one instance and I run the migration the first time, then I try to run it again (same instance of the workbench) and it hangs and does not run. I then exit the workbench and reopen. After that I can run the migration tool again (only once). To run it again after the 2nd time, I still have to exit the Workbench and restart to run it again.

Fixed as of the upcoming MySQL Workbench 6.3.7 release, and here's the changelog entry:

After successfully executing the database migration wizard, executing it a
second time required Workbench to be restarted.

Thank you for the bug report.
