’The system has run out of application memory’

[Anna5C25]

When i try to export my media with the format H.264 and the preset YouTube 720p HD, once it encodes to 70% complete a message pops up saying ’The system has run out of application memory’. I have tried going into File/Project Settings/Generel under "Video Rendering and Playback" and switch the renderer from "Mercury Playback Engine GPU Acceleration (Open CL)" to "Software Only" and the same thing happened where the message appeared at 70% saying "the system has run out of application memory". My laptop also has a ton of storage left. Please help!!

- Do not turn off Mercury Playback Engine GPU Acceleration (Open CL)

- Change 'Optimize rendering ..' into "Memory" (Edit > Preferences > Memory.. ).

- Reboot the laptop before start of the export, and better don't use laptop during export.

Also, disable auto screen lock in the "Power & Sleep" in the Window settings, it's buggy:  https://community.adobe.com/t5/premiere-pro/render-issues-error-code-1609629695/m-p/10079665#M173678
