There's an error somewhere with the game's UI on the latest SMODS version, and given I was the one who made the PR that changes how the scoring API works, I have a pretty big hunch of what's causing it. See the crashlog, and the changed code here: https://github.com/Steamodded/smods/pull/809/files
My guess is that the game fucks up while injecting the score calculator into the UI.
