Faults when importing numba

I have a very perplexing problem that I was hoping someone could help me with. I’m trying to use numba on mac os x Mojave. When I try to import numba, I get various faults. Here is an example terminal output:

This is not something I’ve run into before, and everything I’m used to trying (reinstalling everything, setting different versions in macports) doesn’t fix it. I have uninstalled and reinstalled all the ports that seem like numba should be dependent on them, such as numpy, llvmlite, llvm, and even python3.8. Is there anything else I should try?

I have another computer (same os) that is running numba with no issues, so I can’t figure out what the problem is here. (Unfortunately, I’m not allowed to use this particular script on that other computer, for work-related reasons.)

Any advice would be appreciated. Thanks!
