yeah, your kernel is definitely degrading security features, i guess it is missing some essential apparmor patches …
it gets even worse because you installed it on an official ubuntu install it seems, where the full patch set and the full set of ubuntu default options is expected …
switch to an official ubuntu kernel (6.1 is provided as one of the -oem or -hwe kernels if you have a hard requirement for this version) and it should all work.
