Nsight compute exits with error code 3221226505

Hello everyone, I am having trouble using nsight compute.
I am using nsight integration for visual studio 2022.
OS: Windows 11
GPU: RTX 2060
Nvidia driver: 566.36
CUDA toolkit: 12.6
Nsight compute: 2024.3.2

The Interactive Profile works, but when I try to launch the profiler I get an error.

CONSOLE OUTPUT:

==PROF== Attempting to connect to ncu-ui at 127.0.0.1:50152...
==PROF== Connected to ncu-ui at 127.0.0.1:50152.

ERROR WINDOW:

The profiler returned an error code: 3221226505 (0xc0000409)

PROGRESS LOG:

Launched process: ncu.exe (pid: 9992)
C:/Program Files/NVIDIA Corporation/Nsight Compute 2024.3.2/target/windows-desktop-win7-x64/ncu.exe --config-file off --export C:/Users/user/Nsight_compute_output/1 --force-overwrite --set full C:\Users\user\source\repos\FFT-CUDA\x64\Debug\FFT-CUDA.exe
Launch succeeded.
Profiling...
Process terminated.

What could be the cause? I have tried reinstalling nsight compute and nsight integration for visual studio.

I get the same error even with the basic cuda example project.
I tried running as Administrator

When trying to run ncu from command line, it almost immediately exits without any output.

Thanks to whoever chooses to help me!

Hi, @grande.alfry

Sorry for the issue you met.
Have you tried running “ncu $sample” directly ?

When you say interactive profile works, do you mean you click “Profiler Kernel” and get the report ?

Hi, @veraj
thanks for your answer.

When I try to run the command

ncu .\program.exe -o .\outfile

The command exits with no output and does not generate any files.

On the Nsight Comput GUI, from “start activity”, if I select “Interactive profile” and click “launch” it works.
But if I try to select “Profile” and launch it does not work and gives me the aforementioned error.

Hi, @grande.alfry

Have you enabled the permission for profile ?

Tried your set up internally, can not repro the issue. If possible, please clean current installation, and reinstall again (especially nsight compute and driver )

Also make sure sample can run successfully without ncu.

PS: Please use “ncu -o .\outfile .\program.exe” instead.

Hi,
I have already allowed performance counter access.
I have tried uninstalling and reinstalling nvidia drivers, CUDA drivers and nsight compute several times.
I have tried the newest version of CUDA drivers and nsight compute 2025 but I still get the same error.

What could be the cause? this is a big problem for me, as I need to profile with nsight compute for a university assignment.
