When I edit the C# Unity Scripts, they open in Visual Studio. I've noticed that the autocomplete works on some lines but it doesn't in others.

Here you can see what's going on:

As you can see I get the autocomplete for GetComponent function only when I type inside the line 19.

I also tried this:

By moving the whole Start() function, autocomplete seems to work, but when moving back to the original place, it seems to stop working again.

By further testing, I noticed that autocomplete does not work on lines 11 through 14 and works on any other line.

I tried updating Visual Studio, deleting and recreating the C# Script, regenerated the project files and even reimporting all assets. Nothing worked.
