P: Crash on using Select Subject or Object Selection Tool on Windows

@michaelw9942706 that actually makes perfect sense - when you select that tool it begins to analyze the image to give you results when hovering.

Alright, tired of testing. Last data point for now. Regardless of having SMT disabled, kept getting many crashes. Noticed in the advanced settings I did have gameboost mode checked on, which is a slight overclock. Disabled that and left SMT disabled for now. Have done many iterations of clicking object selection tool within 10+ images with success. It's interesting the action of just clicking the object selection tool results in an instant 15-20% CPU utilization spike without even using it. 

But for now, it seems quite stable. 

If I get motivated I'll try turning SMT back on with gameboost disabled. 

Well, spoke too soon. Crashed again, and it actually popped up a blue screen for a second, wasn't able to see the error before it auto power cycled. Unfortunately it didn't result in a photoshop crash log. Will attempt to use Beta + disable of SMT

Alright additional information, while the beta version is much more stable, over the course of an hour or two last night and this morning.. still had a handful of complete system crashes.

I too have an AMD 5800X. After seeing your post about SMT, I went into bios and disabled it. I swapped back to production Photoshop 25.0 I now no longer have any crashes after about 20 minutes of testing. Looks to be an issue with Photoshop and SMT utilization on AMD Ryzen systems.. at least in the 5xxx series.

The Probem:
My entire computer crashed every time I click on the object selection tool or if I go to select/sky or subject

Things I tried that DID WORK:
Turning off Simultaneous Multithreading (SMT) in my BIOS

Things I tried that did not work:
preferences/performace/disabling my entire graphics card in the

preferences/performace/ unchecking the multithreaded compositing
preferences/Image Processing/Selection Processing / selectingmore stable

My System:
Windows 11(updated)
1 GPU: Nvidia GeForce RTX 3070 (updated drivers)
X570 / Aorus Pro Wifi Motherboard
CPU: AMD Ryzen 9 5950X
2 monitors

Great news on the progress @michaelw9942706 

There is a new Ps beta that was released last night: Adobe Photoshop Version: 25.1.0 20230920.m.2336 7cff1e8 x64

Curious if you update and if it is stable for you as well.

Did end up having one crash with the object selection tool, but in ~30 minutes of use, it's been very functional. 

@CShubert heyyy.. success here..

Used the CCP tool to remove ~13 items -> rebooted. Reinstalled regular PS 25.0 and had the same results of a crash 

Used CCP tool again, removed same ~13 items -> rebooted.. Installed Photoshop Beta strawberry fields.. I seem to be able ot do all the things. 

Ok, let's try this...

Use CCD tool to wipe everything, clean install Ps, restart machine and open Ps... crash?

If so, wipe everything again and install Ps beta, restart machine and open Ps beta... same issue?  Remember, Ps beta is not a trial, it is a full functional app available to any customer that has a Photo or All apps subscription. There is no time limit to using it as long as you have a vaild Adobe photo subscription.
