Does clinfo work for you? I think I have the same issue with Intel HD 520 on fedora 36. Darktable won’t start with opencl (–disable-opencl works fine) and clinfo puts out some info followed by a segfault.
I guess it might have something to do with this issue: ocloc crashes with LLVM 13 #204 - intel graphics compiler.
One of the comments is from the guy maintaining the intel-compute-runtime packages for fedora.
