Media Encoder crash while exporting H264

[fernando alves]

I have a 4k Pro Res 422 master and want too make a HD H264. It is a web serie and has 9 minutes. 

My export set up is:

Format: h262

Preset: High bitrate

1920x1080

23, 976

Bitrate encoding: VBR, 1 pass

Have been trying this for a while. The computer crashes  every single time. It freezes the computer. So I need to turn off and turn on again the computer.  I am using version 14.5 and 13.1.5.

After insist using media encoder, try it in DaVinci and work very well. Faster and smoother than Media Encoder. 

Why does this happen?

Thanks

I'm having this issue with exporting from After Effects. It just freezes after a minute and then crashes.
