Can't apply Adaptive Profile in LRC and also in ACR

In LRC and ACR can’t apply Adaptive Color profile. 
In LRC nothing happened in preview (no image change, but when copying settings form earlier images that used this setting you get error information  “Failed to apply adjustment to following photos. An unexpected error occurred while processing. (1)” then name of image.
In ACR I got “Could not update all AI Settings” error.
It worked on v.14.x version and older ARC. Also if Adaptive Profile was applied it is still possible to edit this image correctly.
Strangely didn’t found problems with other AI features (masking, de-noise, depth blur, etc), that seem more AI heavy.

    Even with this same hardware limitation my former instalation of LRC (14.x) on macOS 13.x worked fine. So it doesn’t seem to be so related to this hardware limits (it maybe not optimal, but was functional). Also switching off GPU acceleration don’t help. And I as mention, my perception is that other AI functionalities should be more demanding than this color profile calculations.  

     

    Adobe is constantly changing the code and AI models used for LR’s AI commands, and new releases of Mac OS can contain updated graphics drivers.  Each AI command uses the GPU in different ways. So it’s not surprising that what used to work in older versions of LR and Mac OS no longer works.

     

    The Adaptive Profile can compute AI masks behind the scenes, so it might be using more GPU resources than might initially seem apparent.

     

    Adobe stubbornly and inexplicably refuses to have LR’s AI commands obey the settings of Preferences > Performance > Use Graphics Processor, even though it would be trivial engineering to do so.

    ​@johnrellis Thank you for replaying. Just wonder that is almost exact to your answer for almost exact case about year ago “Adaptive Color Profile not Being applied” I did read it before posting, but seemed not answering my 
     

    But, and this is big BUT it was different hardware, macOS and LRC version, the sys. req seem same as this one you bring in the answer. 
    Even with this same hardware limitation my former instalation of LRC (14.x) on macOS 13.x worked fine. So it doesn’t seem to be so related to this hardware limits (it maybe not optimal, but was functional).

    Your older Mac’s graphics processor doesn’t meet the minimum system requirements for LR Classic, which requires at least 2 GB (2,000 MB) of graphics memory:

    Each of LR’s AI commands uses the GPU in different ways, and Adobe is constantly improving the AI implementation. So it’s not surprising that some commands work and others don’t, or that commands that worked in older versions of LR no longer work.
