yes if you don't long rest a lot the game scripts will cause crashes... even on good systems because Larian linked the story events to long rest at camp so skipping rests makes them play out of sync
how many hours of play will matter more on smaller setups like laptops and this build still has at least two major patches before they can start working on reported [or unreported script errors]
i think its great you are learning and it will not take long to come to grips with how D&D battles are played
