It looks like #246. It was fixed in v4.5.1.
You can try with the latest AppImage to see if this bug is fixed: https://github.com/TheTumultuousUnicornOfDarkness/CPU-X/releases/latest

Hey,
I just updated CPU-X to Version 4.5.2. It's still not starting, but now I'm getting a different Error:

Your GPU user mode driver is unknown: 4.6.0 NVIDIA 515.76

I also tried the AppImage as suggested, there I'm getting a total different Error:

/tmp/.mount_CPU-X-YrLIzT/AppRun.wrapped: error while loading shared libraries: libthai.so.0: cannot open shared object file: No such file or directory

Thanks for your help.

I do not get it. You have a NVIDIA graphic card and you are using the Intel Iris OpenCL driver?
Can you told us what hardware you have and which GPU is supposed to run OpenCL?
Also, please provide the clinfo command output.

[kkhkkh1]

Sorry for the late answer,
the System which I'm using currently is a Notebook with intergrated Intel Card + NVIDIA. NVIDIA is set as primary GPU, I don't know what's about the Intel drivers, since everything else uses NVIDIA driver's and is working as expected.
clinfo 's output is "Segmentation Fault". That's all it show's.
greetings

Ok, because according to the backtrace, it is loading the Intel (Iris) OpenCL driver.
If clinfo is also crashing, something is not configured properly on your system. I can suggest to remove the mesa package on your system, or rebuild CPU-X without OpenCL support (cmake -DWITH_OPENCL=0).
But there is nothing I can do here.
