I get the same error on the 24.1.1 branch:

Traceback (most recent call last):

Had the same issue. Then I diffed changes and saw this in sentry/sentry.conf.example.py:

-        "BACKEND": "django.core.cache.backends.memcached.MemcachedCache",
+        "BACKEND": "django.core.cache.backends.memcached.PyMemcacheCache",

You need to make the same change in your sentry.conf.py to make it work.

Looks like a duplicate of getsentry/self-hosted#2728, so will close this
