after the verb
A subject is found at the front of the sentence before the verb. However, a sentence structure can hide a subject if the sentence begins with a clause. For example: When the doorbell rang, my dog barked and whined. Dog is the subject in that sentence, despite that doorbell is a noun.
You. You is the subject in that sentence, and it is indeed a pronoun.
No, the object of a preposition cannot be the subject of a sentence. The object of a preposition is a noun or pronoun that comes after a preposition in a sentence. The subject of a sentence is the noun or pronoun that performs the action of the verb.

The action NEVER performs the subject. The subject can perform the action -- this is an active sentence has the word order S V O eg The dog chased the cat. In a passive sentence the action is performed on the subject. The cat was chased
The word "were" in the sentence should be "was" instead. The simple subject of the sentence is "packet", a singular noun that requires a singular verb form. "Chips" is merely the object of a preposition and not the simple subject of the sentence, although it is part of the complete subject.
The action NEVER performs the subject. The subject can perform the action -- this is an active sentence has the word order S V O eg The dog chased the cat. In a passive sentence the action is performed on the subject. The cat was chased

A natural sentence is one that follows the usual subject-verb-object word order in English (e.g., "I eat pizza"). A transposed sentence has a different word order, typically inverting the subject and verb for emphasis or stylistic reasons (e.g., "Pizza I eat").
The preposition in the sentence is "of." It shows the relationship between the subject "he" and the noun "charges," indicating that he was found guilty in regard to the charges.
