Qt Design Studio shut down suddenly

caoc10

Hi everyone,

I've a project developed in QT Design Studio (version before the current one).
After update it to the last version, i cannot simply open my UI files that contains animations and modify them.

Everytime I open the file, the program crashes and goes down.

I have tried to understand what is causing the problem and figured out that if the following code is commented, the UI file opens without problems.

KeyframeGroup {
            target: loginScreen_Base
            property: "opacity"
            Keyframe {
                frame: 0
                value: 0
            }

            Keyframe {
                frame: 674
                value: 1
            }
        }

I've executed it using Terminal and when the program crashes, I get the following error:

QFileSystemWatcher::removePaths: list is empty
QFileSystemWatcher::removePaths: list is empty
Exception: "InvalidPropertyException"
Function:  "parentProperty"
File:      "/Users/qt/work/build/qt-creator/src/plugins/qmldesigner/designercore/model/modelnode.cpp"

"file: /Users/qt/work/build/qt-creator/src/plugins/qmldesigner/designercore/model/modelnode.cpp, function: parentProperty, line: 381"

libc++abi.dylib: terminating with uncaught exception of type QmlDesigner::InvalidPropertyException

Abort trap: 6

I've already reinstalled the entire qt suite a couple of times, and I always get the same error.
I've also tried with a new project, but as soon as I start to use animations, the program crashes with that error.
I've tried also the Windows version (I've been using MacOS) and the problem persists.

I know that I can always skip animations and develop a simple UI, but I rather not do it.

So, if you have any other suggestion, or a possible solution to this, please, help me out to figure what is causing this!
