Please describe your issue in as much detail as possible:

Trying to re-authenticate with PayPal does not work, when clicking the yellow PayPal button one of two things will happen:

1. A black overlay on the page content will appear saying it will redirect to PayPal, and there is a link that says "Click Here to Continue". Usually at this point, a small dialog box will appear where I can enter my PayPal credentials and proceed, but his has not been the case for a few months.
2. The Steam Client will freeze and eventually crash after some time.

Steps for reproducing this issue:

1. Add a game to cart and attempt to purchase with PayPal when Steam says you must re-authenticate with PayPal
2. Click the yellow PayPal button to re-authenticate
3. Either nothing with happen or Steam will freeze

This has been a problem for a few months and is even a problem on my Steam Deck (in Game Mode and Desktop Mode), meaning I cannot buy products on Steam with PayPal outside of my web browser.
