Windows 10: Miracast from PC to Roku locked at 30hz

Hello, I have a Roku Express 2022. I recently got it because I saw that you can stream wirelessly to a TV. My Steam Link died so decided on this because it was the cheapest option.I have a fully updated Windows 11 machine with a Ryzen 9 7900x, 32 GB 6000MT/s RAM, and an RTX 3070 that is on the latest graphics driver update. I'm using the built in WiFi chip in my motherboard for Miracast, MSI B650 GAMING PLUS WIFI. It can run my monitor at 3440x1440p 165hz no problem. My old Steam Link could run 1080p 60hz no problem as well. I have a WiFi 6 router, and I'm on 5GHz. It can stream wirelessly to
