Remove Tool "On Device" feature is NOT using GPU and very slow, Is this a bug that will be fixed or can be fixed ??

In Photoshop BETA the on device remove tool is not using GPU, and although it starts using vRAM it than start using RAM and CPU for a long time.
It does "work”,  no errors, but can take minutes.

Using Photoshop on same PC same picture it works great, faster as cloud.

is this something in the configuration, or reload / reinit required to repair ?
