Adding this as a major bug because it's hard to track down.
With aristotle installed, I see errors on page with a view rendered like:
Deprecated function: str_contains(): Passing null to parameter #1 ($haystack) of type string is deprecated in Drupal\views\Plugin\views\style\StylePluginBase->tokenizeValue() (line 238 of
This is because the overridden views template in aristotle is very out of date.
Update the override of the base template with the one from stable 9.
Probably all of the views template overrides should be updated to be based on the latest versions of those templates in Drupal 10. However a more sustainable way to handle this would be to use preprocess or the default views config itself to add any necessary classes, or to provide custom style plugins if the changes are more significant.
Needs review

Put up an MR for the minimal possible fix - just updating the template from 10.1.x's stable9 template. This removes the PHP notices for me.
