I update QGis to 3.24.3, with this new version, QGIS update Qt library to 5.15.3.

Now when I run my PyQgis App, I have this error:

Cannot mix incompatible Qt library (5.15.3) with this library (5.15.2)

Any idea to resolve it?

  • Hmm, I have the exact same problem on Linux mint, based off 22.04 Ubuntu. The suggestion below doesn't work for me, It just deletes the bindings you need to run pyqgis
