QDS crashes when creating a 3D project

Tested with QDS 4.3 Built on Jul 30 2023 02:33:09

1. Create a new 3D project with target kit 6.4/6.5 or create a empty project with target kit 6.5
2. When the project is created, create another 3D project with target kit 6.4/6.5
3. QDS will crash

UPDATE: In the newest build for QDS 4.3 (Built on Aug 2 2023 02:32:43) after this crash, The QDS kept crashing when I tried to open or create a new project. The crashing stopped when I deleted the "workspace" folder from C:\Users\vivarank\AppData\Roaming\QtProject. Also this bug seemed to disappear, when I deleted from that location all the thing related to Design Studio.
