Media Encoder stops rendering half-way and all settings are greyed out - help!

I'm trying to render a project from Adobe After Effects 2022 in Adobe Media Encoder 2022. I have the up-to-date versions on both of them. I put in all of my settings and click the start render button. Suddenly the render stops and all buttons + settings are greyed out. I cannot restart the render, nor change my settings. I have had no luck finding this problem or any solutions on any other forums. I have purchased the legitimate version of Adobe Creative Cloud and I am a little bit new to all of this. This is how AME looks after it stops rendering.
