The problem is with omissions - leaving out far too many words, even up to partial verses.
Yes the KJV is hard to read being old English - BUT get some old dictionaries from 2nd hand shops (usually cheap).
Get hold of a hard or electronic copy of Strong's Exhaustive Concordance of Hebrew and Greek Words for study help.
Compare what you read in the KJV with other translations to get the gist of the meaning, yes that's fair enough.
But real Bible needs to be based on the older Bible translations, preferably before 1900 for substance and content.
Another true value of the most venerated King James is that [unlike most contemporary versions] the KJV is a
word for word translation. That is every word in the original languages is translated into the KJV.
Not even the Revised Version of 1888 managed to do that.
