Broken Plugin Admin Interface

I am currently running WordPress 5.5.3 with Genesis 3.3.3 and Version 3.4.1.13 (free) of the Smart Slider 3 plugin. Since the WP5.5 update, the backend admin interface for Smart Slider has been broken. Instead of the usual layered and tabbed interface, all of the interface elements just run together in one vertical list. I can still navigate around and edit things, but it is difficult to view. I have been checking for interference from WP plugins, browser plugins, caching, etc. but no luck so far. The actual slider functions correctly when used, it’s just the admin GUI that is messed up. Other plugins do not show this issue. Should I just remove and reinstall the plugin? Thanks.
