This is a guess based on the very little information I know of yours and the Pi400 power management but a transient voltage increase on the Pi Power input may be triggering a brown out condition that is used normally to provide a clean reset to the CPU on slow rising power supplies.
Your capacitor may help by slowing the transients but may also require a resistor to create a LP filter. May need to be more creative too.
