Substantial delays/lag when sharing screen

When I share screen in a meeting the screen share can be 20-30 seconds behind for the viewers on the other end. I get 500mbps up and down on my network with about 35 ms ping so I don't believe network side of things is the problem. As for device I am using it is an M1 Macbook Pro I use for work. I also have tried zoom on an M1 Pro Macbook Pro that I own personally. Both should be sufficiently powerful for zoom so I am really at a loss as to what the issue might be. Any ideas as to what I can try or where to look next would be great.
