Qualcomm driver can not handle the optimized SPIR-V that Blender creates. According to their driver engineers this is an issue in shaderc. As we are late in the release process they asked us to disable the optimizations. In Blender 4.4 we are planning to update shaderc what might fix the issue. This should be retested after the update.
