Photoshop not applying changes made in Camera Raw

Having the same issue as well with a Dell G7. Worked fine up until 2024 updates. I've had to go back to prior versions just so I don't go crazy. In one of the updates it seemed to have been fixed but then it stopped working again.

I'm having the exact same problem and it's driving me mad..

I'm having the same issue since the update to PS 2024, everything worked fine with the prior 2023 version. I'm currently running the most recent update (version 25.3.1) and it still doesn't work.

Dell G7 7500; Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz; 

Nvidia GeForce RTX 2070 w/MaxQ Laptop GPU

Windows 10 Pro.

Photoship 25.3.1;

Camera Raw 16.1

To get this out of the road and to set expectations... The Adobe Camera Raw plugin which opens the raw sensor data before Photoshop isn't (exactly) the same thing as the Camera Raw Filter which is only for rendered RGB data (not raw sensor data).

I am not familiar with FotoStation, you mention opening files directly from there and that it is archiving software... Perhaps that's part of the problem?

Is an .XMP sidecar file being created/updated with the same name as the .CR3 file in the same location?

Supported camera models here for ACR raw files (CR3 appears 24 times, but you didn't state the exact camera model):
