CPU Sets rule ignored after waking from sleep?

I'm using Process Lasso on Windows 11 and created a CPU Sets rule for one specific application so it only runs on a selected group of cores. It works correctly after a fresh boot, but after the PC wakes from Sleep, the same application sometimes starts using all available cores until I manually restart the process. Has anyone seen CPU Sets rules stop being enforced after resuming from Sleep? Is there a setting in Process Lasso to automatically reapply CPU Sets after wake, or is this a Windows scheduling limitation?

Does the current CPU Set of the process change, or just the cores that end up used?
