PMB can you explain your analysis as to why you said that inertial force does not depend on mass. Einstein mentions that spacetime warps around massive objects and the more heavy an object is the more spacetime is warped meaning more gravity.

Now even though gravity depends on mass in general relativity as per the above analysis it is not a force because objects simply travel on the straightest possible paths through spacetime, called geodesics. The paths only seem curved because of the warping of spacetime.

So it doesn't take any force to keep something moving on a straight line. Which means that gravity is not a force.

I am eager to know the reason why you said gravity or more precisely inertial forces dont depend on mass.
