P: Camera Raw as a Filter (not the plugin) freezes Photoshop on use

Hi. Thank you everyone for the patience regarding this issue. Photoshop 25.9 has been released and while it does not contain any additional changes to address this issue, it contains a diagnostics mechanism aimed at helping us better understand the root cause so that we can fix it.

@Marshela37315835hi27, @absolute_cooks, @Amy247863851ryi, and anyone else still seeing this issue, it would be helpful if you could do the following for us (it involves enabling the new diagnostics mechanism, reproducing the issue, then sharing the diagnostics).

Enabling the diagnostics mechanism and collecting the diagnostics both involve locating the Photoshop settings folder, which should be here:

• Mac: /Users/<your username>/Library/Preferences/Adobe Photoshop 2024 Settings/
• Win: [Installation Drive]:\Users\<your username>\AppData\Roaming\Adobe\Adobe Photoshop 2024\Adobe Photoshop 2024 Settings\

Here are the steps to follow:

1. Update to 25.9
2. Add the following line (exclusive of the quotes) into a PSUserConfig.txt file in the PS Settings folder: "LogACRFilterProgressFreeze 1". This page describes how to setup the PSUserConfig.txt file: https://helpx.adobe.com/photoshop/kb/enable-optional-extensions-photoshop-cc.html.
3. Quit PS if it is running
4. Launch PS
5. Go to Help > System Info.
6. Verify on the first line that version 25.9.0 is listed.
7. Scroll a handful of lines until you see "PSUserConfig entries:"
8. Verify that you see an entry in that section that says " - U LogACRFilterProgressFreeze 1"
9. Reproduce the issue. This should caue some diagnostics info to added to the bottom of the PSErrorLog.txt file (see later steps).
10. For good measure, maybe kill Photoshop, restart it, and reproduce the issue again, or even a couple of times. It's possible we'll get different diagnostics info (I'd be interested in having you repo for both the Camera Raw Filter case and the "open an ARW file in Photoshop" case @Amy247863851ryi)
11. Look in the same Photoshop settings folder for a file called PSErrorLog.txt and open it.
12. Search for the first line that contains "LogACRFilterProgressFreeze". Select everything from the line above it to the bottom of the file and share that here on the forum.

Mac example of PSErrorLog.txt addition for a single repo case:

On Windows, the 3rd line will instead be a series of lines that are numbered 1, 2, 3, 4, etc.

Thanks again to everyone for their patience and the assistance in getting to the bottom of this issue.
