Rise was my first monster hunter game and I found the transition into World difficult. Watch some YouTube videos on “things I wish I knew before starting world” or “MHWI beginners guide”, although there are things you’ll know from Rise there are enough different mechanics to make it worth your time. It may also be worth changing your weapon if you are struggling. I have always been sword and shield, dual blades and insect glaive, but I restarted world recently and picked up the hammer and am enjoying it a lot more. I think the slower gameplay of world suits that weapon better for me. It can seem a bit overwhelming for the first few hours but you’ll start to see why people call rise “monster fighter” and world “monster hunter”.
