Fedora 35 KDE live freezing on click

I always wanted to get started with Fedora but didn’t feel confident. I’m now used to Ubuntu and feeling confident to switch to Fedora, but I’ve some issues like 2/3 VS Code instances getting almost 90% of RAM, the android emulator almost unstable even freezing the PC (nouveau/ Nvidia 390/ Nvidia 418). I don’t even think about the android studio.

However, I flash live Fedora 35 KDE (not installed yet). It’s freezing if I click any icon from the taskbar, I don’t know if it’ll work after installed or not.

My focus is on productivity, basically, web development and flutter mobile application development. I use VS Code, Firefox, Chrome, and android emulator most of the time.

Please suggest to me how to set up a smooth development environment.
