I was having this exact same problem on a Macbook Pro m4, however it was a big deal for me since I do heavy use of direnv and it was completely unusable (bash is used by direnv to load its stdlib, and was segfaulting).

Updating to latest macOS version (Sequoia 15.5 from 14.X) solved the problem for me.
