3 finger click -> middle click crashes the app

Alpha version also has this issue.
If i map 3 finger click to middle click app will crush after few seconds of start or first 3 finger click
but if i map 3 finger tap it works, thats how i'm getting along for now. Please fix this its very annoying.

Weird, that seems to work fine here.
Can you check whether there is a crash report in the macOS console app?
