Layer error: Image.reduceRegion: Too many pixels in the region. Found 13758042614, but maxPixels allows only 10000000. E - google-earth-engine

Question

Hi I'm new to google earth engine so I am struggling with a (probably) quite basic error.
Here is my code - the issue is with the Sunglint Corrected layer.
I'm trying to correct sentinel-2 images for Sunglint so that I can remote sense seagrass.
I think the issue is something to do with incorrect scaling, although I'm very unsure how to fix this. Plz help!
