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

@michaelw9942706 have you submitted Crash Reports to Adobe via the CR tool? If so, do you use this email on the forum, is that your Adobe ID email... we ask because we can look up your crashes to get to the team to see what they see.  Also, what version of Ps beta or Ps release are you seeing this please.

@Kevin Stohlmeyer whole pc crash. As state before, fortunately it is not a gpu or psu issue this is an adobe photoshop issue. I can run furmark on the gpu all night long, max out utilization for his doing AI art generation on stable diffusion, and or game the latest and greatest on end. 

6 months of a brand new 4090 / psu, this is the only application that has an issue and I use my system 10 hours a day for both work and play, and this is definitely the only one that has ever caused a complete system crash. 

@michaelw9942706 does your whole PC crash or just PS? PS should not crash your entire computer, just the software.

If the whole PC crashes - thats pointing towards your physcial graphic cards. Perhaps reseating them and running diagnostics on them is in order.

@Kevin Stohlmeyer just did all 3 of those. Click the object selection tool, select anything within an image, immediate PC crash. 

Hi @michaelw9942706 have you changed any of your preference settings in Photoshop to try and resolve?

If not here are some suggestions. I would do one at a time restarting PS after each to see if it improves:

1.Go to Photohop Preferences/Image Processing and change all settings to "More stable" and "Cloud" (not device).

2. Go to Photoshop Preferences/Technology Preview and check “Disable Native Canvas”. 

3. Go to Photoshop Preferences/Performance and uncheck "Multithreaded Compositing".

4. Go to Photoshop Preferences/Technology Preview and check “Use Older GPU Mode (2016)”.

I was hopeful.. installed studio drivers rebooted my system, restored photoshop to defaults, used the selection tool, immediate pc crash on a 1024x1024 simple image. 

I am running the gaming drivers, but I'd think turning off GPU support would alleviate issues? 

I'll see if I can test studio drivers to compare later on tonight. 

@michaelw9942706 focused on one part of your comment - are you running the Nvidia Gaming drivers or Studio drivers? PS prefers the Studio drivers for GPU.

I've completely turned off GPU use in the performance / image processing menu, switched to "old GPU support", switched to "stable", switched to cloud processing. Regardless, many tools including color replacement, selection, healing and occasionally remove background will force a complete PC reboot. Lots of issues with this program for some reason. Have had it crash my system just by attempting to open a simple 1024x1024 png file. 

Fortunately / unfortunately it's not my psu. It's brand new 1200 watt corsair with the new rtx connectors to pair with the 4090. I can max out the 4090 on stable diffusion ai generation, local gpt4all or gaming at 4k on max settings on all the games. This is purely an adobe issue.
