Issue with Norton and Windows defender

Hi, I am currently very tired and going to bed right after I write this so I am going to make it quick.

I am having a big issue with Windows defender forcing a scan, which is going into my open programs (Video games mostly) and crashing them, causing me to lose progress and possibly corrupt the saves.

The message in Event Viewer is this, The Windows Security Center Service could not stop Windows Defender.

I am not sure what to do and would like some help as I am getting super tired of it happening.
