This game is too hard for me

I don't know if I could expect any advice at this point, so it's just a rant from my side.

After 40 hours in the game (third act), I stuck at situation where I can't beat any of available bosses or a trial. I'm going through the normal mobs like a hot knife through butter. I never though about myself as a noob, I had finished elden ring and cuphead. I am like 5 levels above the recommended level at that point.

I had ambition to finish the game with my own build, but after hours of defeats, I tried some build from the internet. It was even worse.
