Getting alot of console errors on fresh wordpress install

Hi there,

I have installed a fresh wordpress install (latest version 6.0.3) and just using the default theme (Twenty Twenty-Two), and it’s showing a lot of errors in the Console tab when creating a new page/post (screenshot here: https://snipboard.io/CDqdtP.jpg).
Examples:
blocks.min.js?ver=658a51e7220626e26a92a46af5c2e489:3 Block validation: Block validation failed forcore/button` (Object).

Content generated by save function:

<div class=”wp-block-button has-custom-width wp-block-button__width-100″><a class=”wp-block-button__link”>Watch my latest videos</a></div>

Content retrieved from post body:

<div class=”wp-block-button has-custom-width wp-block-button__width-100″><a class=”wp-block-button__link wp-element-button”>Watch my latest videos</a></div>`

I have no plugins installed, just using the default theme and it’s already showing many errors in the Console tab. Is this a core issue? It’s pointing to this ‘blocks.min.js’ file in ‘wp-includes/js/dist/’
