2FA & Interstitial issues

PHP 8.4, nGinx 1.28.0
Multiple issues. First and foremost. Cannot login like normal. I login to my site, it goes to wp-login.php and throws a WP Error page stating: Failed to create interstitial state. and does nothing else.

Cannot set on any account. That one throws a WSOD, with this in the logs.
