[QGIS-Developer] Loading netCDF4 seems to crash QGISv3.34

[afernandez]

Hello QGIS Developers,
This problem still persists with v3.34 and it's easily reproducible by simply opening the python console and typing:
import netCDF4 as nc
I opened a new ticket QGIS crashes when importing netCDF4 · Issue #55787 · qgis/QGIS (github.com) <https://github.com/qgis/QGIS/issues/55787> . In the meantime, I'll also try installing v3.32 and checking whether the crash also happens or not.
Thank you.

Hello,
I'm upgrading from v3.30 to 3.34. However, QGISv3.34 keeps crashing when trying to import the netCDF4 module (never had this issue with v3.30). More specifically, the log reads:
