Bug summary

During a recent GitHub Actions workflow for unrelated pull request#29721, the following error appeared:

E           gi._error.GError: gi-invoke-error-quark: Could not locate g_option_error_quark: dlopen(libglib-2.0.0.dylib, 0x0009): tried: 'libglib-2.0.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibglib-2.0.0.dylib' (no such file), '/usr/lib/libglib-2.0.0.dylib' (no such file, not in dyld cache), 'libglib-2.0.0.dylib' (no such file) (1)

Code for reproduction

This occurred for Python3.12 and Python3.13 on MacOS 14:

• https://github.com/matplotlib/matplotlib/actions/runs/13788406404/job/38561789129
• https://github.com/matplotlib/matplotlib/actions/runs/13788406404/job/38561789705

Actual outcome

See the error in the main description and linked build logs.

Expected outcome

The tests should pass as expected (the error appears to be atransient failure to locate/load a dynamic library file).
