Freezing after 30 minutes and wall ride mission glitched

Annoyed. It’s annoying because it runs smooth, I can do 2 jam sessions, and multiple missions, then when I load into one, it freezes. Close the game, reopen every 30 minutes isn’t relaxing or fun. And the wall ride mission, 3 simple tasks, get the bearings, wall ride the tunnel, and flip trick the stairs. Make sure you slip before getting the last bearing, but even with completing all tasks, one is still unchecked. And that’s also after doing it 3 times for it to fix, and yet no prevail.
