Hey,
this appears to be a problem with the intel-oneapi ICD. A quick-and-dirty solution would be (re)moving the file at
/etc/OpenCL/vendors/intel-oneapi-compiler-shared-opencl-cpu.icd .
This should fix it. Just be aware you don’t need it for something else or just keep a backup of the file.

best regards,
Daniel :slight_smile:
