Checkout not loading with products added to cart nor payment processing with quick links in Magento 2.4.7

I just can’t seem to wrap my head around this with my checkout and payment processing not working. I’m running Magento 2.4.7 and my store runs well. I can view, choose and add products to my cart. If I try to go to my checkout, the page processes endlessly and it never loads the customer information form and so on. If I try to click on the Paypal quick link while viewing a product, the popup flashes an goes away. Now if I inspect the page, it shows me several CSP errors, unknown property warnings, and “A resource is blocked by OpaqueResponseBlocking, please check browser console for details.” I know the warnings are one thing but what’s with the CSP? I am using a stock setup for 2.4.7 and added the basic information with nothing custom. I have no clue why I can’t even get to my checkout let alone get to processing a payment. I’ve read some things about a whitelist but have absolutely no clue where to begin there. Any help would be great as always.
