Unity don't work and it's impossible to repair the problem.

I am forced to abandon unity
After updating Unity to the latest version, the templates that I had downloaded have stopped working, not only can I no longer download them but also the new templates that I download do not work. Not even reinstalling Unity solves the problem. I can’t do anything except leave the engine.

This is not even a question, if you’re here just to complain about an engine, then try to contact someone in Unity or leave a review…
And this isn’t a phone app, if you perform an update on your system, then you have high risks of something stopping working…
Unity is an awesome engine and even i updated several times and had no problem…
Have a good day.

ok if something stops working but reinstalling everything doesn’t fix the problem. I am not saying that Unity is not a fantastic engine and I am sure that many people use it successfully, but if something abnormal happens there is no way to fix it. This is something to report I think, it’s not a complaint. Good day to you too.
