Question Z623 Right Speaker is not working only on my PC

[CozyGuunter]

So I got a Logitech Z623, I plugged it into my pc and only the left side is working. I checked the sound settings for balance issues and mono audio to be sure, and that wasn't the case. So to make sure it was not a hardware defect I tested it with other sources and it worked perfectly on my phone, iPad, and Laptop, it just won't work on my PC. I updated my Realtek as well. I'm not an audiophile so I'm not sure what to do, I look up almost everything and nothing is helping. I ordered an AUX with 3 rings instead of 2, I don't know if that will help cause it came with an off-brand 2 ring AUX but I don't think that's the issue since it worked on other devices.

I tried to unplug the left side and play an audio file, and I could hear a faint sound from the right speaker. However, once I plugged the left side in, the sound immediately went away. If there is anything else I could try, please tell me, because I'm going crazy.
