Admin Dashboard Blank after WordPress Update

Hi,

After upgrading to WordPress 5.4.1, I found that the WP Admin dashboard is completely blank, other than the side bar. Every page I visit is blank. The site itself still seems to work fine. I was able to isolate the issue to this plugin; if I deactivate it, the WP Admin dashboard works fine, but if I enable it again, the dashboard stops working. I’ve checked the logs and there are no errors being generated by PHP, so I am stumped as to why this is happening. I am using the latest version of this plugin (Version 1.4.3).

Any help would be appreciated, thanks!
