Conflict after last update

I submitted a ticket 4 days ago via Averta as suggested in this forum, but I have yet to have any response. Here is the full message:
Hello,

I believe the Master Slider (free version) plugin was updated today, and subsequently, my website broke. It took some digging, but it is clear that there was a major problem with the plugin. I have deactivated it for now, but it is a big part of our mobile version of the site, so I’m hoping a bug fix is coming very soon. If you can advise on what the issue is and if there’s going to be a fix, it would be much appreciated. To help, I am using the Porto theme, with Elementor Pro and this is the error Master Slider is causing:

Parse error: syntax error, unexpected ”j’ (T_ENCAPSED_AND_WHITESPACE), expecting ‘)’ in /home/mikava5/public_html/wp-content/plugins/master-slider/admin/includes/classes/class-msp-admin-assets.php on line 438

Thanks in advance for any assistance.
