My django project has this issue after I updated my redis to version 5.4.0. It seems that the HiredisParser that I was using in my PARSER_CLASS in the redis configuration could not be found in this update. After taking a look at the change log, it seems the issue is a rename of the HiredisParser class from HiredisParser to _HiredisParser.
So a simple change from this:
"PARSER_CLASS": "redis.connection.HiredisParser"
to this:
"PARSER_CLASS": "redis.connection._HiredisParser"
should fix the issue.
Note that if hiredis package is already installed you can remove the whole line completely in your django cache configuration as it will by default select _HiredisParser if hiredis is installed.
