I doubt it. They had such large reserves of hulls before 2022 that it wouldn't have made economic sense to make new ones, and knowing Russia they wouldn't have kept the tooling needed to restart production in workable condition. And it's usually more difficult to restart production lines than it was to set them up the first time because the supporting infrastructure and trained workforce often aren't there anymore. Admittedly, a tank hull is basically just a welded steel box so it should be comparatively easy to start making more even if you're having to start over from scratch but Russia isn't exactly a model of competence and efficiency. They're also really bad at addressing problems before they become crises and have a stunning capacity for regression.
More than that, like most authoritarian or third world countries they prioritize propaganda value over practical concerns (to the extent that on more than one occasion they've provided the Ukrainians with detailed BDA in order to claim bridges were intact xaxaxaxa). Simply put, if they were producing new tank hulls we would have already seen video of Shoigu or Putin 'inspecting' the plant.
