What parts should I upgrade next?

Hello lovely people of Reddit. I have been lurking for awhile now and was afraid to ask you guys in fear of rejection. Anyways my question is. My pc is a few years old now and I'm looking into upgrading some of the parts if not all I've listed if needed. I don't know specifically what I should upgrade too. I'm running windows 11 and it has its moments when it's VERY SLOW. Any advice is appreciated. Also I don't know anything about AMD GCs or CPUs so I primarily use Nvidia or Intel. If anybody has any ideas that'd be great. Thank you guys. Have a great day!
