Hi and welcome to WordPress Trac!
I cannot replicate this issue, what php version are you using and is this a fresh WordPress installation?

[sabernhardt]

Somehow the $block_attributes variable is null in wp_apply_alignment_support() for your site, and the stack trace mentions the Site Logo block.

Line 48 could check is_array() before running array_key_exists(), but it would help to know how the $block_attributes can be any other type.

$has_block_alignment = is_array( $block_attributes ) && array_key_exists( 'align', $block_attributes );

Trac is used to track bugs of the WordPress Software, your issue does not appear to be an issue with WordPress itself but more likely a faulty plugin, theme or webserver configuration.
However there is a place to go for your issue: I recommend you to go to the WordPress support forum to get help for your problem: ​https://wordpress.org/support/forums/
