Mac Studio 2022, M1 Ultra shut down problem

My mac studio (2022, M1 Ultra) has been randomly shutting down almost constantly. A few times it has been restarted, it only stays on for about 40 seconds, then shuts down. I have unplugged all the cords for a few hours, sometimes it can be turned back on and used for a few hours without suddenly shutting down, but sometimes it doesn't.

I have taken it to the Apple service center (twice). They checked it and said everything was working fine. The first time, in May, after the test, it worked normally for about 3 months. Then the shutdown happened again, and it happened more often, sometimes I couldn't turn it on for 30 seconds. The second time I took it for service - in August, they still said there was no problem. But only 2 days after the second test, it happened every day.

The staff said they had run Apple's tests on the hardware, it passed. They said the software in the machine was conflicting so it's leading to this situation. Now this situation happens all day long, I can't tell when it can turn on and use. While I took it to the warranty check, they all said there is no error.

The software I use is only Adobe's apps, Blender, Google chrome, nothing else. All are licensed software, paid for annually. I also did not download any malicious 3rd party software, or access any suspicious websites/links. And when i erase all data and reset the mac, this situation still happens.

I don't know what to do. Buy a new mac? I think it will be a waste of my Mac studio with quite high configuration - M1 ultra/20 cpu/64 gpu/128gb/4t. That is probably the last solution.

Has anyone had the above problems, or does anyone know if there is a way to fix this situation? Thanks a lot.

Mac Studio, macOS 15.6

one thing that caused trouble on older Mac Pro was the power cord connection to the computer. I suggest you power down, remove the cord, and JAM it into the computer socket.

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.

Use Etrecheck Pro for free:

http://Etrecheck.com

The amount of data you get can be daunting. If you POST your report, some Readers here are willing to look over those reports, and can provide valuable insights.

then start a reply on the forums, click on the "additional text" Icon, and PASTE

Hi! Thanks for your reply.

I am talking about Mac Studio (M1 Ultra, 2022), not Mac Pro.

When I brought it in for warranty check, I provided the machine's cord for the technicians to check. They said that my cord had no problem and during the 7 days of checking, my machine did not suddenly turn off once. I changed the new power plug for the machine, but the problem of sudden shutdown still happened continuously.

The strange thing is that when they reinstalled the operating system, without any third-party software, they did not detect any problems. But when I received the machine and installed some software that I have been using for the past 3 years (all are copyrighted software), these problems arose continuously.

I tested the EtreCheck software and attached the report below (this test was when the machine did not suddenly turn off, maybe I will test it a few more days later).
