QML application is Crashing using CANVAS2D on QNX.

[SU_AV]

We are implementing an QML application using Qt 6.8.3 which will run using the QNX 7.1 on target that uses ARM board.
In our application we are drawing a line on using onpaint{} of CANVAS2D over a grid png image in the background of this CANVAS2D. This drawing is continuously happening as soon as the coordinates are coming from another interface.

While drawing this application is getting crashed. But when we remove the grid png image and starts drawing using CANVAS2D then we did not observed any crash.

Pls help us to figure out the issue and with solution.
