If would be useful if you could verify that with the non-backports kernel it also works again. If that's the case, could you try newer versions (6.1.15-1, 6.1.20-1 and 6.1.25-1) to find the newest kernel version that still works? A `git bisect` would be best, but grabbing these intermediate versions (from snapshot.debian.org) is the quickest way to narrow the range.
