    There is no short circuit. This is a negative layer (everything with color is without copper). The problem what you may have with these GND Vias is that they may not have enough cooper (big part of the VIA is outside of the copper area) - maybe that is what Altium is trying to say?

    I have the doubt that these two points are the cause of the short circuit !! what is your opinion?

    This should not make short circuit.

    BTW: Why do you need thermal relief on VIAs? You may end up with ... hmm ... with the mess what you can see on your PCB. Problem is, if you have many VIAs in one place, some VIAs may get disconnected because of holes in the thermal relief.

    Try to enable direct connection to see if you will keep getting errors / warnings.

    Please, could you attach screenshots from layers and Vias? Based on the list I am not sure what the problem is.

    Starved thermal on GND or on power in PCB 4_layers

    these errors can make me a short circuit (between GND and Power ) in my PCB which consists of 4 layers ( top , power , gnd , bottom )
