Premiere stops rendering

I am trying to render my college project since yesterday and my premiere pro doesn´t finish the render process. It starts normally and then stops at 14%. I looked to task manager and the use of my GPU (RTX 3050 8Gb) falls to 0% when it arrives to 14%. I tried to update my GPU drivers, uninstall and install again premiere pro, I looked for updates, I cleaned the cache files, tried to render in other sequence, changed the location of the files and none of this worked. Even Media encoder can´t make the render, it stops at the same point. 

A feel weeks ago I rendered another version of my project and it worked. But now that I´ve made some changes and it doesn´t render anymore. 

I don´t know if the error is related to this, but I am using Adobe Dynamic Link in this project. I made animations in After Effects and export to premiere to make the sound design and other corrections. But as I said, last time it rendered normal.
