Comment:

 Hello @namithjawahar,

 Welcome back to WordPress Core Trac! Thank you for reporting this issue.

 Doing some backtracing in the Gutenberg repository:

 * Gutenberg 13.9.0 added the `get_template_hierarchy()` function but did
 not protect it from a conflict with Core.
 * Gutenberg 14.1.0+ added the protective guard (i.e. wrapped it with
 `function_exist()`.

 In WordPress 5.8, [https://github.com/WordPress/wordpress-
 develop/blob/trunk/src/wp-admin/includes/update-core.php#L1643 a function]
 was added to deactivate an older incompatible plugin. This function was
 updated in WP 5.9. It was not updated in WP 6.1.

 For WP 6.1, a fix is to update the Gutenberg version number from `11.9` to
 `14.1`. This change should avoid a fatal error for anyone updating to
 6.1.1+ with an older version the Gutenberg plugin.

 Moving this into 6.1.1 milestone.
