If clinfo does not work, how should dt do? 
About the mentioned compiler problem: dt uses the systems default llvm compiler and trusts everything up to 13 as correct.
Also - and probably more important - Fedora 36 is not stable atm. This is one of the errors that can be expected on a beta system as only a few applications make use of OpenCl so a bug might get un-noticed longer than others. Also, the linux kernel used is very fresh and intel regularly contributes with OpenCl and driver fixes.
