Sometimes you just have to swallow your pride and watch a couple walkthroughs and character build videos to get into a game from someone who has mastered it; just to get over that hump.
This is why I always bounce hard off RPGs yet love immersive sims with RPG-elements. Traditional CRPGs feel so hostile to players new to the genre, or those without a lot of free time. I would think difficulty sliders could help, though not sure if that's seen as sacrilegious or something.
BG3 does have difficulty levels but even the lowest can be deadly. The game intends for you to save very often, even in combat. F5 is your friend!
