I believe this is an issue caused by incompatibility between qtpy and the latest pyside 6 6.4.0 release. We should pin the pyside version to 6.3.2 until this is fixed by a new qtpy release.

indeed, downgrading PySide to 6.3.2 does it. Thanks Lou!

The fix (issue 373) will be in QtPy 2.3.0: https://github.com/spyder-ide/qtpy/milestone/38

Should be ok now, Qtpy 2.3.0 is out.
