Need an Education Lawyer to help me prove my innocence ( falsely accused)

I am a university student who has been accused of two false academic dishonesty violations cases from the same professor. In the first case, the professor said that my solution, along with other students for a part of a question, is wrong in a unique way similar to Chegg. In the second case, the school investigator claimed that I had contacted someone to do the work on behave. I asked to meet him via zoom; I showed him how I solved the question during the meeting, and I denied the accusation. Later he sent me a WhatsApp conversation with my phone number. The image shows a conversation between a person asking another one to solve a homework question for him. I need someone to help me to prove my innocence to them. I am very engaged in the course as I never missed a lecture or an office hour. Always on time, and I am engaged in the course Discord group as well. I am not sure who is trying to frame me in the second case, but for the first one, the TA gave me insight into the solution, and I was in a study group with other students. I am innocent; I have written two essays to defend myself. The first one contains 1500 words, and the second one contains 2000 words. I have proofreader it myself. it has been checked it for grammatical and spelling errors by me over and over. What I need is a legal consultation on why someone would do something like this to frame on, and how could I prove my innocence appropriately. Note: I prefer to write my own words what I need is a consultation only as I may take it to court if I did not receive my justice from the university.
