Mac forking error

[HashNotAdam]

When I run one of my RSpec tests—and only a specific one—I receive the error:

objc[24658]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
objc[24658]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

I'm happy to help debug this, but I'm unsure where to start, sorry.

My stack is:

• M2 Mac
• spring (4.1.1)
• rails (7.0.8)
• rspec-rails (6.0.3)
• pg (1.5.4)

I can confirm this is happening on a colleague's (identical) Mac

I've tracked this issue down to GoodJob (we're running v3.19.4). I'll move this issue there
