Finder over time can break and make the system unusable?

Without more information, it's very hard to say exactly what caused your issue. The Finder "breaking over time" isn't a likely cause, though.

It's not clear if you're asking for help or if you have already resolved your issue. If you want help, you'll need to give us a lot more information.

There are many reasons why the Mac might misbehave. A Finder that doesn't respond properly can be a symptom of any number of problems, including data corruption, conflicting software installations, drive failures, etc.

As @IdrisSeabirght has pointed out, without more specifics and details about your particular problems, putting the finger on the actual culprit is near impossible.

FYI, reinstalling the OS is a fix for very many different problems including, apparently, whatever problem you have experienced.

Thx you but finder isn’t always responding like other systems ;-;

What does that mean? Unless you give specifics about the problem, there's not much anyone can say.

Are you possibly referring to the Search function within Finder?

So what is the problem?
