Beats Flex only playing through right side on iMac?

I have two beats flex. One of them works completely fine on my Mac, iPad, and phone. The other works completely fine on the iPad and iPhone... but not on the Mac.

For the Mac, it only plays audio through the right side. It doesn't matter if it is through YouTube, through my videos on Apple Photos, or Apple Music; only on the right side and not left.

I have a base model M1 iMac.

I have tried closing all my apps on the Mac and turning it off and turning it back on again.

I have tried factory resetting my beats flex.

I am the big sad, please help.
