@anlino @macmanx I had time to debug now. Seems to be the following snippet for removing version parameters, that is making problems with WP 6.2 and Bjork theme in functions.php

// Remove wp version param | css and js
function remove_wp_ver_css_js_code_paste( $src ) {
    if ( strpos( $src, 'ver=' ) )
        $src = remove_query_arg( 'ver', $src );
    return $src;
}
// for css style file urls
add_filter( 'style_loader_src', 'remove_wp_ver_css_js_code_paste', 9999 );
// for js script file urls
add_filter( 'script_loader_src', 'remove_wp_ver_css_js_code_paste', 9999 );

@anlino It seems to be no plugin problem, but a problem with my functions.php’s individual actions and filters. As a workaround I rename the functions.php and then edit in the site editor.

Right, thanks for the remarks.
However, many WordPress Websites do not have a Permission-Policy header at all (and even no Security header), so overwrite might not apply.

@wpkube Thanks for the Update. Works perfect in new Version: 20210409.
