MagicException : File 5.41 supports only version 16 magic file, magic.mgc is version 14

Question

I'm getting this error of Magic version on my Virtual Environment when I run python3.8 manage.py migrate on my Django REST API.

I've already done the following after activating Virtual Environment:

• pip3 install python-magic --upgrade

Here is what exactly is shown at the very end.

magic.MagicException: b"File 5.41 supports only version 16 magic files.`myproject/misc/magic.mgc' is version 14>

There are several line of errors like the offset error but I have taken a few of them and posted it due to character limitations on stack.

Need help here since I'm stuck and unable to proceed ahead.

The problem is related to the python version.If you use python3.8 generate mgc file, you must use python3.8 to load this mgc file.
