media encoder don't work

Hi,

I have the full pakage Adobe.I'm using the Photoshop, Premiere Pro and Animate. After the installing of new versions, lot of problems. Changed the Premiere to old version and now it is OK. The Media Encoder do not work when I try to export the Animate file to MP4.

My desktop has RAM 8 GB, video 2 GB, and I use to work well in the other version of the Adobe programs. Now it´s impossible. When the Media Encoder try to render, the RAM goes to   97% of use and the task doens't complete. Please, help me in this. Thank you.
