Can anyone help me understand?

Hi, I have a MacBook Pro 15 2016, it has been cleaned and the screen has been replaced a year ago by Apple.

The computer is in perfect condition, never dropped, never contact to water.

Lately apps opening has been broken and slow (??)
I have not installed updates or new apps recetly.

Like today, booted the Mac, all good and smooth, opened iBooks, mail, opens instantly, Safari and Logic Pro x bounced for 3 minutes before opening!

I did the Mac OS diagnostics and it found nothing, maybe to early because in-out at the beginning as nature, so in line I'm guessing hardware?

Any advice helpful.
Thanks to fellow forum members.

Is your drive HDD or SSD? How full is the drive? It is best to keep at least 20% free for better performance.

Nope, its not that, I have 60gb space untaken. 🤔

You might want to consider backing up your files on an external drive, erasing the SSD, reinstalling macOS, then moving files back over.
