just get the error cant set fps max while connected, do i actually need to go to the menu every time?

ok so I haven't done a speed run for a while. today I re-installed live split and now I'm getting this weird error that says 'object reference not set to an instance of an object' and then I wait a few minutes and it says 'the given key was not present in the dictionary' when activating auto-split. I've searched around for like two hours but cant find a fix can somebody help.

is the LAG glitch aloud on inbounds legacy

ok I sound really dumb but I cannot figure out how to set up splits on portal
