Failure during WP 5.3 Update

Hi, I got the exact same issue since I updated to 5.3. Can’t figure out how to fix this issue. Any help would be appreciated.

download 5.3 manually and get the 2 missing files (you’re only see the first error)
class-custom-image-header.php
class-custom-background.php

I do that. Thanks.

Hi,

I notice you did not solve it yet? As already suggested you should upload the missing file: wp-admin/includes/class-custom-image-header.php

hi,
same here.
I am getting errors for missing files, then i upload them from the new release but again i get the missing file message.
Now i have uploaded the class-custom-image-header.php file in the wp-includes directory but still get

Seems you’ve uploaded file in wrong folder..

It’s wp-admin > includes
