Pixelated bevels

Hello, I am trying to make these letters I applied a bevel to not be pixelated around the edges. I have tried ray tracing as a vector, high quality, etc which creates the clean edges, but then I get these black lines around the letters and some inside the letter. I'm not sure how to get rid of them or how to not make that happen. How can I vectorize these letters so that all the edges are clean?
