I've just had a look through the journal while running both versions of the kernel. 0000:04:00.0 which is the network card in question is in its own group with kernel 6.4.0-150600.23.14-default - group 40. On the newer kernels, it is showing 11 devices under group 32, including 0000:04:00.0, the group concerned with this problem - most of them have nothing attached. I have attached a few screenshots showing between the 2 kernels. Don't know if this helps.
