This thread is resolved. Here is a description of the problem and solution.
Problem: I have created a custom taxonomy in Types, and I would like to assign it to a custom post type. In the panel "Post types to be used with this taxonomy" on the taxonomy editor page, I cannot see any post types. Instead, I see the standard WordPress admin error message "There has been a critical error on your website. Please check your site admin email inbox for instructions." In the notification email I can see the following message:
Fatal error: Uncaught Error: Call to undefined function mb_strtolower() in /path/to/site/wp-content/plugins/types/vendor/toolset/types/includes/classes/class.types.admin.page.php:689
The stack trace log follows this message.
Solution: The error must be resolved by your hosting provider, because the Multibyte String PHP extension mbstring is not active on your server. This extension is required for Toolset to function correctly.
