- DRA drivers: the resource slice controller sometimes didn't react properly when kubelet or someone else deleted a recently created ResourceSlice. It incorrectly assumed that the ResourceSlice still exists and didn't recreate it. ([#132683](https://github.com/kubernetes/kubernetes/pull/132683), [@pohly](https://github.com/pohly)) [SIG Apps, Node and Testing]

- Fixed: during the kube-controller-manager restart, when the corresponding Endpoints resource was manually deleted and recreated, causing the endpointslice to fail to be created normally.
