Updated site to 5.9 & posts page has broken?

Hi,

My WordPress site uses the following:

• Header.php file in the theme’s files.
• Footer.php file in the theme’s files.
• Apart from the Posts Page, the rest of the site makes use of Gutenberg blocks.
• The posts page uses the site’s index.php file at wp-content/themes/meow/index.php

When I updated the site to 5.9, the posts page no longer looked the same. I checked what file loads when the posts page is viewed in the browser:

• Before the update to 5.9, the site loads: wp-content/themes/meow/index.php.
• After the update, the site loads: wp-includes/template-canvas.php

I thought WordPress was supposed to be future-proof. How can I make use of index.php, instead of template-canvas.php, when the site is updated to 5.9?`
