Persistent 'TypeError: 'NoneType' object is not iterable' - Mac

After numerous failed attempts at Flux Generation with all iterations of the flux model (including nf4), I cleared the field and did a completely fresh Forge install, (SDXL, SD1.5 etc. still all work perfectly fine as they did before), but Flux still constantly hits me with the 'TypeError: 'NoneType' object is not iterable' message.

I also tried the: "set COMMANDLINE_ARGS= --disable-xformers" to no avail, before completely uninstalling XFormers - as I read another post suggesting there may be an issue with it, but none of this has resolved the issue sadly.

I'm on a Mac Studio with an M1 Max chip and 64GB or RAM, so I don't know if there's maybe a more persistent Mac-specific problem that others are also running into? as I've seen the above xformers fix helped a lot of PC users.

No source file, test, or entry point is identified in the report. First reproduce Flux generation on the M1 Mac environment and capture the complete traceback and model/settings details; done means identifying the failing component and confirming the error no longer occurs without regressing the reported working SDXL and SD1.5 cases.
