White Screen of Death: Odd Issue with Pages Not Loading after Clicking Links...

I've been using GP for the past few years and just decided to migrate two new sites over in the past 24 hours and they both have an odd issue, especially on mobile, when you click a link in the nav bar, and the site just goes to a white screen and hangs... Then I need to just refresh the page to get it to load. I didn't think much of it however now the exact same thing is happening on the second site I just installed the theme on... Have you seen this before? Here are the domains: https://ridetheairbag.com/ https://simplewebhelp.com/ Thank you again so much, I absolutely LOVEEEEE your lightweight theme and plan to keep migrating more & more sites over this year.
