HOW can I update industrial themeforest theme?

We first updated our site to WordPress 5.6 and then ran into a black screen problem.
We installed the enable-jquery-migrate-helper plugin.
And we updated all our plugins.
But the problem was not solved.
We thought the problem might be with our site theme.
Disable the previous theme and reload the theme(OUR THEME IS: Industrial - Factory Business WordPress Theme from )

The black screen problem was fixed when you clicked on the site,
But when entering our admin, we encounter this error:

"Fatal error: Cannot redeclare wordpress_importer_init() (previously declared in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wordpress-importer/wordpress-importer.php:51) in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/anps_theme_plugin/importer/wordpress-importer.php on line 47

( we can connect with FTP to our site, after deleting this theme we access our WP admin! but we need to install this theme to work our website correctly.
how can I fix this problem?
is it possible to solve this problem, by updating the theme?
