Zoom recording has super low pitch and speed of both speakers: help!

hi! This is the second time that it happens: we record the podcast with the usual mics and settings, normal speed etc and still the episode plays my voice as if it were a ghost's. So slow, un-natural and low pitch. I sound like a man.

I tried to play it a bit faster but then I sound like Mickey Mouse with a low voice. I tried to change it with Garage Band and no luck. I am using an iMac.

Is there any reason why Zoom does that?

I've been using it since 2018 every single day and we have not changed any settings. I am starting to think I need to move away from this platform as it's so unreliable.

Thanks!
