Media Encoder Fails to render for the last 4 months

Hard to tell without the project and media. Does the dircet export in AfterEffects work correctly? Does AME not working apply to sending After Effects projects or also to transcoding files directly in AME?

Using Windows 10, and it happens on my fiancees PC and i am unable to share the files

Which OS are you using? Would you be able to share the project/media for looking intto your issue. I can send you a private message in this forum with instructions.

Everything is Current, updated and matching. there are no 3rd party plug ins, and the project does not seem to matter, no matter what im making in After Effects, how simple or short it is, After Effects Eats up over 70% of my availible memory (48GB of Ram) I7 processor, 500GB ssd and 2 Terabytes of storage. Media Encoder fails to Render ANYTHING and Everything! its been month and months of this Crap! nothing I try works to solve any of these issues, i have tried every fix i For the love of God can somone please HELP!! ADOBE!!! FIX THIS, i know im not the only person to experience this issue. I just need to Render my Projects like Adobe intended. Im like a week away from never touching adobe again.

Ok, you never mentioned your are talking about an AE project. To render complex AE project, especially you mentioned Maya, so I guess there might be 3rd party plugins involved, you need to have AE installed on the same machine where you are running AME with all the required 3rd party plugins. For PremierePro Projects and PremierePro Mogrts AME can standalown process this. For AE projects/comps not. 
If it start rendering and fails in the middle, please check the AME Error Log to see if there are more information in it. (AME->File->Error Log)
Currently you didn't mentioned the AE and AME version. Are you on the latest and are they matching? If not, please update to the latest available for both. If you are using expressions, ensure the App language of AME and AE is the same. You can manually change it in AME, if they are not matching.

ill do my best to understand what you said,

so I made a 15 min video in AE, its only 2 layers with 0 effects or anything fancy going on, im trying to send it through Media Encoder, h.264, 30fps, cleaned up the Cache for AE and ME, it will render for a few minits then it just fails ⚠️. No idea why

Please can you provide the used AME version and OS version, what is your workflow (Send a Project from PPro, import direct into AME etc. ) and what is your input and wished output format + the used preset? In some cases it is good to clean up all actual and older Preferences by just renaming the Adobe Media Encoder Folder in your Documents Folder to avoid older preferences will be used.
