Can't Get Past "hashcat (v4.2.1) starting..."

For some reason I can't get hashcat to start or do anything. No matter what command I throw at it, it just says "hashcat (v4.2.1) starting..." and then dies, can't even get it to produce an error. Output below:


c:\hashcat>hashcat64 -a 0 -m 9400 hash.txt pass.txt
hashcat (v4.2.1) starting...


c:\hashcat>hashcat64 -I
hashcat (v4.2.1) starting...


c:\hashcat>




I have verified that my GPU driver is up to date and that I have the latest hashcat files. I'm trying to run it on Windows 10 x64. I feel like I'm missing something simple because what's odd is if I use the The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) app from the Windows store, that at least detects the CPU and runs.

I admit, I am a n00b, so if any more info is needed to help troubleshoot, I'll try my best to provide it. I'm at a loss for what to try next since I've never had issues with any of the other machines I use hashcat on. Any help is greatly appreciated. System info is below in case it helps.
