i believe the problem is still the broken intel opencl GPU driver (this problem is as old as the intel integrated cpu/gpu devices) you have to stick to CPU opencl drivers (in my case i can force hashcat with options -D -d1 to use CPU)
your device
Device #1: Intel(R) UHD Graphics
try using intel opencl drivers for CPU only (you will need to deinstall the UHD graphics driver beforehand, if you just have a laptop without a separate gpu this approach will not work for you)
