Well, you could try to remove pocl and mesa and other OpenCL runtimes that are not recommended on https://hashcat.net/hashcat/ and install the Intel OpenCL driver for your AMD CPU (yeah, that's not a joke, as far as I know the Intel OpenCL runtime works best for most CPUs!)
This is of course not easy at all to do on The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) because of all the dependencies, therefore you might need to also remove the debian hashcat package (that has/had some very strange dependencies on open source OpenCL runtimes) and download hashcat from https://hashcat.net/hashcat instead.
This is why we do not recommend messing around with The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) and just use ubuntu (which is supported/recommended by most OpenCL drivers themself) and the binaries from https://hashcat.net/hashcat instead.
Anyway, you could always mess around your linux distribution that much until everything works as expected (or nothing at all works anymore) to come up with a running OpenCL environment + latest hashcat from https://hashcat.net/hashcat. It might be much more difficult for some distros and that is why some are not recommended here, because we do not see the point why users should feel the pain in struggling so much with just installing OpenCL+hashcat
