File field (Chrome only) – not triggering upload window

I have added a file field to my C7F with the following code in the form template:
[file your-file]
And the following code in the Mail template under File attachment:
[your-file]

When I test the form in Chrome by clicking the “Choose File” input, nothing happens (i.e. there is no window that triggers to select a file). ONLY in Chrome does this issue happen. Firefox and Safari work just fine.

What I tried:

• Deactivating all plugins
• Current theme is a child of Twenty Twenty, so I tried switching to a different theme
• Clearing site cache as well as browser cache and opening site in an Incognito window
• Added this code to the functions.php file

add_action('wpcf7_before_send_mail', 'save_application_form' );

function save_application_form($wpcf7) {
    $submission = WPCF7_Submission::get_instance();
    $files = $submission->uploaded_files();
}

I’m completely out of ideas at this point and would appreciate any help.
