Hi thanks for your feedback and sorry you’re having trouble between BP & PHP 8.0. I also use it but can’t manage to reproduce your issue. You can fix this trouble easily though. You simply need to add the following code:

<?php
remove_filter( 'block_editor_rest_api_preload_paths', 'bp_blocks_preload_paths' );

into a bp-custom.php file and put it in /wp-content/plugins as explained here: https://codex.buddypress.org/themes/bp-custom-php/
