Grids not working in PHP 7.4.7

Hello,
I work for a Technical College and we were testing a new stack on our local machines. One of us could not get the Grids Plugin to work, and we discovered that that machine had a newer version of PHP on it (7.4.7) where as the rest had 7.3.10. We tried several other things, but what finally worked was downgrading the PHP version.

Our production is scheduled to go to PHP 7.4.x this fall. Could you test the plugin for this version?
