My Macbook pro Mid 2012 on Sonoma is really slow. Wallpaper not loading, safari including other applications are slow. Websites cannot be played like YouTube and crashes. Do you guys know how to fix this?

Installed Sonoma On OCLP and also installed all patches it worked a couple of days running smooth, but one day I opened my macbook and it started to be really slow.
