Extra space on right side of website / Custom font not working on portfolio

I noticed there is a white space on the right side of my website that I've tried getting rid of for a few months with different codes, but nothing seems to work. 

Also, the custom font I've uploaded doesn't seem to work on the portfolio page but it works everywhere else.

If anyone can help me it would save my life thank you!

Wait actually now it's giving me extra spaces on the left & right of the footer where the Instagram block is. 🥲 Is there a way to fix it?

Find this code in Custom CSS

#block-yui_3_17_2_1_1655250587902_7974 {
    padding-bottom: 0vw !important;
    margin-: 0vw !important;
}

change it to

#block-yui_3_17_2_1_1655250587902_7974 {
    padding: 0px !important;
}
