Awareness is an abstract noun. It is not something that is countable, or which exists in a concrete sense. It is therefore most common not to use any article at all.
That said, the use of articles with abstract nouns is not straightforward.
Abstract nouns can be used with an indefinite article (a/an). Few native English speakers would understand the difference between 'an awareness' and 'awareness', let alone English learners, but there is an explanation here and here. In essence, they are largely interchangeable, but with, perhaps, a slight additional specificity when using the indefinite article which is similar to saying 'a kind of'.
In your sentence, saying
"so it is crucial to develop a kind of awareness"
would not be accurate. You want people to have general awareness, not a specific kind of awareness. So I would probably lean towards no article if I was being extremely pedantic. But either option is fine.
It is also possible to use abstract nouns with the definite article when referring to a particular instance of the noun. In your sentence that is not be appropriate.
[PS. As @Jason Bassford notes, 'force' is an abstract noun too, but in the universe of Star Wars, 'the Force' is a proper noun referring to a specific type of force used by Jedi, and therefore the definite article is appropriate.]
