I am working on my personal project. 5 PCB. Among of 5 PCB there are 2 PCB has an issue.
On the PCB if I test continuity with two point which dont have any electrical connection each other but multimeter showing Mega ohm resistance.
This is 4 layer PCB, what mistake can be made by me on the PCB?

On the same terminal another PCB has different resistance
