site error caused by JupiterX plugin

Need help.
When the JupiterX plugin updates, it always crashes my site.
I’ve been advised to reach out to the developer of the plugin.
Here is the text of the error.

20 PHP Fatal error: Uncaught Error: Call to undefined function jupiterx_upgrade_link() in /nas/content/live/genesisspace/wp-content/plugins/jupiterx-core/includes/customizer/settings/pro/popup.php:17\nStack trace:\n#0 /nas/content/live/genesisspace/wp-content/plugins/jupiterx-core/includes/customizer/settings/settings.php(82): require_once()\n#1 /nas/content/live/genesisspace/wp-content/plugins/jupiterx-core/includes/customizer/functions.php(52): require_once(‘/nas/content/li…’)\n#2 /nas/content/live/genesisspace/wp-includes/class-wp-hook.php(288): jupiterx_core_customizer_include(”)\n#3 /nas/content/live/genesisspace/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array)\n#4 /nas/content/live/genesisspace/wp-includes/plugin.php(478): WP_Hook->do_action(Array)\n#5 /nas/content/live/genesisspace/wp-settings.php(523): do_action(‘init’)\n#6 /nas/content/live/genesisspace/wp-config.php(121): require_once(‘/nas/content/li…’)\n#7 /nas/content/live/genesisspace/wp-load.php(37): require_once(‘/nas/content/li…’)\n#8 /nas/co in /nas/content/live/genesisspace/wp-content/plugins/jupiterx-core/includes/customizer/settings/pro/popup.php on line 17

Can you help me understand how this can be corrected?
