Repeated internet downloads when using Photoshop Camera Raw Filter

I’ve recently got a an Asus V16 laptop (Intel Core 7 240H, RTX 5070, Windows 11), and have just installed Photoshop on it. This seems to visibly work, but when I open Camera Raw Filter, an internet download keeps happening in the background consuming internet bandwidth. The download repeats every one to two minutes, and about 200Mb each time.

From what I can see with Resource Monitor it seems to be downloading something from “server-18-244-140-14.lhr50.cloudfront.net” or very similar and at the same time, I can see data being written to a file “%APPDATA%\Local\Temp\41” or some other number. I am guessing these are related.

The other thing is that if I check in "%APPDATA%\Adobe\CameraRaw\Logs\Camera Raw Log Latest v1.txt" it has the error "*** Error: Failed to validate the tmp file. ***". This appears each time the download happens.

Also, if I close Photoshop mid download, I also see a couple of lines about “feature sets” in the log file:

“*** Error: Failed to validate the tmp file.  ***
Starting termination of cr_sdk...
Number of active model download feature sets to be cancelled: 1
Cancellation of all feature sets completed at Time: 179 ms”

If cancelled between downloads instead it has:

“No active model download feature sets to be cancelled.”

I’ve installed latest video drivers, removed and reinstalled creative suite, and tried temporarily deactivating antivirus, discreet GPU, and GPU acceleration in Camera Raw, but none of this has worked so far.

I wonder if anyone has seen this and might have any clues of how to fix. Any help would be much appreciated.

Thanks, Andy.
