SmartCrawl can't pass from 65% even if the SEO scan is restarted

When running an SEO Scan on SmartCrawl, it goes up to 65% then it gets stuck.

The process was restarted 2 times and it started running fast but it got stuck at the same percentage.

max_execution_time was changed from 30 to 300 but got the same result.

Site with staff access enabled.

Thanks in advance.
