I have applied patch #207 from the issue https://www.drupal.org/project/drupal/issues/2784233: → Allow multiple vocabularies in taxonomy filters to support multiple vocabularies in the taxonomy filter on an exposed view.
The patch works correctly. However, I encountered an issue when changing the Exposed Filter Widget to Checkboxes/Radio Buttons in the Exposed Filter Settings. The filter does not work as expected because the Term IDs (TIDs) from multiple vocabularies are not preserved correctly.

Allow multiple vocabularies in the taxonomy filter
Needs work
.
Create a view with a taxonomy term filter using two or more vocabularies.
Expose the filter and select Checkboxes/Radio Buttons as the Exposed Filter Widget.
Try filtering content by selecting terms from different vocabularies.
we can use array_replace instead of array_merge
$flat_options = array_replace($flat_options, self::flattenOptions($choice));

I have updated the flattenOptions() function to correctly handle multiple taxonomies and preserve term IDs when using checkboxes or radio buttons in the exposed filter. Please review the attached patch
