Can capacitors create short circuits?
Definitely possible, e.g. in case of broken MLCC, altough open circuit is more likely. PCB shorts are possible as well. You can try to locate the short by supplying a limited current to the board (e.g. 1-2 A, whatever applicable) and measure trace/plane voltage drop with a sensitive multimeter.
Confusion about capacitors
The capacitor is considered a short-circuit for sufficiently high frequency components relative to its capacitance. That''s how it acts as a filter. The lower frequencies see it as an open circuit and ignore capacitor, but the
capacitors acting as short circuit | All About Circuits

While the term, "short circuit" is only applicable for the initial microseconds or milliseconds or seconds after application of the voltage source

How do capacitors behave in a DC circuit after a short time?
Capacitors behave as open circuits in a DC circuit after a short time. When a capacitor is connected to a DC circuit, it initially behaves as a short circuit, allowing current to flow through it. The time it takes for a capacitor to charge up and behave as an open circuit depends on its capacitance and the resistance of the circuit it is

How can I quickly and safely discharge a charged
As long as you''re dealing with the sorts of capacitors typically used with bread boards, you can probably short it with copper wire, as others have mentioned: 1 uF * 1mOhm = 1 ns discharge time. If it only has 42V on it, these formulas say

6 FAQs about [How to charge a capacitor when short-circuited]
What happens if a capacitor is a short circuit?
(A short circuit) As time continues and the charge accumulates, the capacitors voltage rises and it's current consumption drops until the capacitor voltage and the applied voltage are equal and no current flows into the capacitor (open circuit). This effect may not be immediately recognizable with smaller capacitors.
Why does a capacitor act like a short circuit at t 0?
Capacitor acts like short circuit at t=0, the reason that capacitor have leading current in it. The inductor acts like an open circuit initially so the voltage leads in the inductor as voltage appears instantly across open terminals of inductor at t=0 and hence leads.
What happens if a capacitor is uncharged?
Assume the capacitor is initially uncharged. When the switch is pressed, the capacitor behaves like a short circuit since there is no voltage across it. The charge starts to accumulate, and the current in the circuit is limited only by the resistance R. So, the initial current is V/R.
What happens if a capacitor is discharged through a low resistance?
The high current through a low resistance causes significant heating due to the power dissipated by the ESR, determined by P = I^2*R. This heating degrades the capacitor and can cause long-term damage. You should always discharge a capacitor through an external resistance to limit the current and minimize heating.
What is the difference between a capacitor and a closed circuit?
Capacitor: at t=0 is like a closed circuit (short circuit) at 't=infinite' is like open circuit (no current through the capacitor) Long Answer: A capacitors charge is given by Vt = V(1 −e(−t/RC)) V t = V (1 − e (− t / R C)) where V is the applied voltage to the circuit, R is the series resistance and C is the parallel capacitance.
How do you know if a capacitor is a short-circuit?
This can be determined by analysing a capacitive circuit as though the capacitor was an open-circuit, and an inductive circuit as though the inductor was a short-circuit, because that is what these components behave as when they've reached "full charge," after an infinite amount of time.
