Describe the bug

There seems to be some issue with QGIS 3.20 in Mac, related to Qt signals from certain widgets. Plugins that worked fine in other versions and that work in 3.20 in other platforms, cause QGIS to crash on QGIS 3.20 on Mac.

The error is related to plugins, but its behaviour indicates that it must be a core or packaging issue.

How to Reproduce

Attached you can find a minimal plugin, which is easy to inspect (one single file with less than 70 lines), and which can be used to reproduce the error. It adds a menu at "Plugins->Test plugin->open widget", which opens a widget with a single checkbox. Clicking on the checkbox causes QGIS to crash.

The plugin works fine in 3.20 on platforms other than mac, and in older QGIS versions on any platform. On 3.20 on mac, it crashes.

Similar code (creating a widget with a checkbox, connecting its stateChanged signal, etc...) works fine if run from the console. Only when it's part of a plugin, QGIS crashes when the signal is emitted.

This appears to possibly be the same issue I have with the add spreadsheet layer: #44484

Does anyone have any idea how to fix?

just noticed that this happens to crayfish & qgis2threejs too (probably as described with any plugin that has some signal/slot in pyqt used in runtime?)

Still an issue in the new 3.20.3 package. Happens for me clicking on a QPushButton but not when clicking a QToolButton. Happens with some QComboBox as well, but not some others, and number/text edits seem fine. Think it maybe where widget signals are connected to slots, unconnected widgets seem OK? Dump of each type below.

@volaya @jlayt @purplecacti @Neofin can you please test with the nightly build, e.g. https://qgis.org/downloads/macos/nightly/qgis_nightly_master_20210916_124111.dmg

The solution was to bump the sip/pyqt/qt to the versions that talk together in qgis-deps-0.9.0
I am tempted not to spend extra time for u 3.20 version to use the new set of deps as it is going EOL in month...

Tested and can confirm this is resolved in the nightly.

In two minds about not updating 3.20, I can appreciate it will save you a lot of work, but we have people using 3.20 as it resolves other issues in 3.16. At the moment they keep having to switch versions mid workflow. Then again, we have other issues we're waiting for 3.22 for as well...

Some 5-6 weeks is a long wait, and it is the first link on the downloads page, so most people downloading the Mac installer for that time will get a crashy install soon as they use a plugin, which is a major use case and not a great impression.

That's a plugin bug, needs to be reported to the plugin author

@jlayt I understand your concerns. Isn't possible to use nightly builds instead of 3.20 for the time being in your team?

@PeterPetrik I guess I could get Munki to spoof it as a 3.20 update, but 3.22 has only just gone into feature freeze so I'm not sure it's stable enough yet to take that risk! Maybe when hard freeze kicks in.

@jlayt let's think about it the other way for a minute. What makes you think that if I just compile 3.20 with a completely new set of libraries (different python, sip, proj, ...) do a small smoke test myself, and publish it on the official download page it would be safer? There could be any other new bug introduced like you would not be able to do coordinate transformations correctly or anything else. And it would not even go through the nightly-FF-testing period as the current 3.22 release ...

I'm observing those crashes with 3.20. I had the same crashes with 3.16, but I had a workaround: explicitly setting QT_QPA_PLATFORM_PLUGIN_PATH:

export QT_QPA_PLATFORM_PLUGIN_PATH=/Applications/QGIS.app/Contents/Plugins/platforms/

That no longer has any effect on 3.20
