I'm having the same issue on Fedora 38 with Cura 5.3.0.

Edit: Apparently the 5.3.1 AppImage from Github works fine, so this might be a packaging issue?

Sounds a lot like a packaging issue. I've seen those errors before on my local dev env from source.

Hey @TahaAbbasi-Hashemi,

Thanks for your report 👍
I'll bring it up to the team to see what they can do to improve it.
Fingers crossed 🤞

I'm using Fedora 38, and having same problem.
Waiting for solution. too ;)

PS: Installed by dnf package manager
appimage, opens (excecute) and not show main window

That ColorImage on line 30 of .../site-packages/UM/Qt/qml/UM/SimpleButton.qml should probably be UM.ColorImage. And there should be an import UM 1.5 as UM statement near the top of the file.

Strange that it crashes for you (as it should) but not for the majority of users.

Yeah!
I edited the file:

sudo nano -c /usr/lib/python3.11/site-packages/UM/Qt/qml/UM/SimpleButton.qml

1- add "import UM 1.5 as UM"
2 - add "UM." on ColorImage

import QtQuick 2.1
import UM 1.5 as UM

MouseArea
{
id: base

hoverEnabled: true

property color color: "black"
property color hoverColor: color
property color backgroundColor: "transparent"
property color hoverBackgroundColor: backgroundColor
property alias iconSource: image.source
property real iconMargin: 0

property alias hovered: base.containsMouse
property alias backgroundRadius: background.radius

Rectangle
{
 	id: background
    anchors.fill: parent
    color: base.containsMouse ? base.hoverBackgroundColor : base.backgroundColor
    radius: 0
}

UM.ColorImage
{
 	id: image
    anchors.fill: parent
    anchors.margins: base.iconMargin
    color: base.containsMouse ? base.hoverColor : base.color
    visible: source != ""
}

}

And it Works!! Thank you so much

One more doubt, would i, add UM. on Rectangle line too??

[fieldOfView]

Thanks for testing. I will make a pull request so this fix can be incorporated in the next release.

Rectangle is a standard QML element, or actually part of the QtQuick package. ColorImage is defined by the Uranium package, which is imported as UM. That's why ColorImage should be prefixed with the UM class.

See Ultimaker/Uranium#874

I'm loving the troubleshooting here.
