Django 4.1 added a system check to find duplicate template tags at startup. If easy-thumbnails and sorl-thumbnails are installed in the same project, it will detect the possible clash and will exit with an error. This happens even if the tags are not used in any template.
SystemCheckError: System check identified some issues:
ERRORS:
?: (templates.E003) 'thumbnail' is used for multiple template tag modules: 'easy_thumbnails.templatetags.thumbnail', 'sorl.thumbnail.templatetags.thumbnail'

I've added a minimal reproduction here: https://github.com/MarcoGlauser/template_tag_conflict Simply run a manage.py command like
makemigrations
