That loop should be broken - but in such a way as not to "kill" a good connection to the wells in the semiconductor. The resistance to the guard ring should stay low, and current density should not be perturbed. For simple structures/layouts, you can inspect this visually, and decide where to do the metal break.

Why do electrical current only flows when it is a closed circuit?
It is not necessary for the charges to flow only when the wires are making physical contact with each other, the leakage current and the arcing are the example of the same but in the case of arcing this requires the huge potential difference between the two points, if this potential difference becomes too large then this cause the air to become ionized which makes …

What''s the point of Vcc and Vee closed loop in op amp inverter
In this application, the capacitor should break the connection between the two points (in the sense that there is no signal transfer between the two points). But it cannot do so in series (an inductor can do it); therefore we connect it in parallel to the "receiver" point (i.e. between the point and ground, as a shunt).

How is a capacitor implemented in Kirchoff''s Loop Rule?
Kirchhoff''s voltage law (or loop law) is simply that the sum of all voltages around a loop must be zero: $$sum v=0$$ In more intuitive terms, all "used voltage" must be "provided", for example by a power supply, and all "provided voltage" must also be "used up", otherwise charges would constantly accelerate somewhere.
Why can''t electrostatic field lines form closed loops?
$begingroup$ So the particle will differ in (ie would have gained) Kinetic energy when it comes back to the same point, in case of a closed loop. But Kinetic energy at the same point should not differ as displacement and so velocity and so Kinetic Energy gained would be zero when the particle comes back to the initial point.

Why does a capacitor connected to AC and high impedance act …
You have an unchaged capacitor with 0V over it. There will always be 0V over the capacitor, no matter what voltage you set the left plate, because there is no current to charge the cap and change voltage of the cap. If you do form a loop, like connect the loose end to 0V, the cap would have current through it.
