Some help would be greatly appreciated.

Your Ready state has a duration of 0 tics, which causes an infinite busy-loop that ultimately kills GZDoom because it cannot process anything else. I recommend setting that to 1 tic.

[Graf Zahl]

Same for Select and Deselect. While these will eventually terminate, this isn't safe.

[Gez]

Note that there really isn't any reason to call A_WeaponReady several times per tic. For A_Lower and A_Raise, I can see an use; even if there are better ways to achieve the same effect; but A_WeaponReady will not do anything special he second or third or fourth (etc.) time it's called in a given tic.
