Sounds like the keyboard can't handle that key combo. This is very common in modern and even older (but cheap) keyboards. Usually you are ok with a 2-key hold, but the third key is usually the problem. Certain keys will work while others will simply not register.

Man, I used to play Mortal Kombat with my brother head-to-head on the same keyboard, and we were both doing moves and blocking without trouble. That keyboard probably handled 6 simultaneous keys without issues.

I actually thought this might an issue at first and went and tested the keyboard on a site and I was able to hold 6 buttons at once. The site was keyboard test space or something like that. I did try it with different keys with the same result

I remember that issue even on an actual DOS machine when I had the CD version. I could only do special moves with 3 keys, but anything that required 4 presses at once was not feasible on ps/2 keyboards.
