Template in Block Themes?

BBpress keeps loading the empty index.php in the TwentyTwentyTwo Child theme I’m working on, which loads a WSOD.

I can’t get any of the template filters to use one of the html files, so temporarily have it working with the index.php file as:

wp_head();
block_header_area();
block_template_part( 'page-inner' );
wp_footer();
block_footer_area();

And… its almost all working? But, this can’t be the right way to get it to use the new default page template in the block theme.

Thoughts? Ideas? How can I get it to use the new theme templates?

Thanks!
