How do i solve OpenCL Platform?

I've been trying to use oneAPI for over a month, but it always gives this error:

OpenCL platform ID is empty
OpenCL platform name is empty
Failed to find any of these OpenCL platforms:
Intel(R) FPGA Emulation Platform for OpenCL(TM)
Intel(R) FPGA Emulation Platform for OpenCL(TM) (preview)
llvm-foreach:
icpx: error: fpga compiler command failed with exit code 14 (use -v to see invocation)

In my research, I discovered that I need the Intel® FPGA Add-on for the Intel® oneAPI Base Toolkit, but I can't find this package anywhere, and when I search on Google, I'm redirected to FPGA Support Package for Intel® oneAPI DPC++/C++ Compiler, I downloaded it, installed it and it always returns the same error, can someone help me!

When this is not the error this appears:
