Probably lack of oil if nothing else, is it sparking and chain stretching a lot?
Most likely if one side is sharpened slightly different to the other but then you say it's new, unless it got blunted on whatever wood you're cutting because of high mineral content.
The plates and bar where it is clamped should be clean, the oiling hole cleared out and the channel needs to be cleaned out, sometimes it can seem clean but a little stone can stay lodged and mess everything up.
Basically once it starts to curve at all in the cut it is tempting to carry on but you're better off taking it out and making it cut right, starting a new cut if necessary. Seems time consuming but often it saves more time to start off again, having a spare bar and a few spare chains becomes the best solution.
whenever I change stuff, i usually check the oiling by running the saw at higher RPM , and it coated the end of a log pretty quickly.
blunting- that makes sense, but the cheap electric saw I bought last week dropped through without issue.
trash in the (channel?) if the bar makes sense. I didn't look at it very closely, but did change the bar/ chain and have similar results again.
I stopped as soon as the cut turned, pulled out, looked and wondered then tried again in a new spot. same result. I was very confused by the results repeating in different places, with new hardware.
note,,, the battery saw I bought dropped through it several times without issue, until the battery was dead. no turning. this makes me thing there's done kind of issue with the husky saw, but I don't know enough about saws to know what that could be.
