If the blade tracks fine before you start cutting, but starts moving hard to one side after you start cutting, it’s likely a blade issue. It’s tough to see if there’s any pitch buildup, but that will cause the blade to twist because the pitch hits the wood before the side of the tooth. Since it’s a set-tooth steel blade, they’re also very sensitive to hitting anything metal on the sides because it ruins the set.

Have you aligned your fence to the blade yet? If so you could test with a thin piece of plywood or MDF to verify setup. If your fence is perfectly aligned to the blade and you cut in slowly only an inch or so before stopping the saw and not moving the wood, the back of the blade should not touch either side of the kerf.

I nearly ruined a $140 carbide-tipped Laguna Resaw King by starting the saw before lifting the tensioner, and then I stepped on the brake in a less-than-ideal reaction. The brake caused the blade to slip off the wheel and scrape against the side of the table, and I had to send it back for sharpening to get it to track right again.
