Restore freezes after restoring wp_options.sql

Greetings,

thank you for creating this plugins, which has helped us greatly.
There is, however, a glitch when restoring, as the process stops after wp_options.sql.
We already optimised the database, but to no success.
Any pointer would be appreciated.

You can find the log below (uploaded to chat, also)

Thank you.
