Do you have a OpenCL.dll somewhere in C:\System32?

[ma-sadeghi]

@isuruf Yes, I just checked.

That's probably interfering here. Moving that OpenCL.dll would fix this issue, but might break some other software.

That's right, I renamed the file and everything worked just fine. Any idea why do I have OpenCL.dll in the first place? Does it get installed automatically when I install NVIDIA drivers?
