MATE Desktop won’t open Chromium

I launched an EC2 instance based on the Amazon Linux 2 with .NET 6, PowerShell, Mono, and MATE Desktop Environment AMI on a t3.large instance and successfully accessed the MATE Desktop environment through my RDP client - I got to the desktop, clicked on the button on the lower left hand corner and navigated the menu to open Chromium. I clicked on the Chromium button, but Chromium didn’t launch. I can open other desktop applications in the menu, such as Caja and MATE Font Viewer, but Chromium won’t open. The Applications menu does close after I click on it, just like the other apps, but the other apps open and Chromium doesn’t. Am I doing something wrong?
