Animate cc recording content to media encoder won't export and not responding for a long time

Hi there I'm an animator working my project but the issue is when I try to export my Animation to media encoder loads slow and when reached 59% it's stops moving and when you click on it the window will not respond I tried restarting laptop and uninstall animate cc nothing worked  even the u 2020 doesn't respond to  when it reaches 100 and freeze I don't know what is the source of the problem is I tried closing the file open again and every time you export it will stay slow and freeze and not responding does anyone one know how to fix it issue because I worked hard in my project and it gone to waste could it do of my computer ram ?
