DS sometimes crashes when opening test project

Tested with 3.5 RC from staging. Opening the attached test project sometimes shows the error message as in attached picture and soon after crashes, sometimes I get an error message about flowview but DS doesn't crash.

I could not reproduce in my own build. I was able to reproduce with RC with these steps:

• Launch DS
• Create a new 3D project, qt6.3 target
• Once opened, close it from menu File -> Close all projects, do not close DS
• Open the attached test project
• For a moment there is an error message visible, then DS crashes
• If I then re-launch DS and open the test project again, it does not crash but I sometimes see an error about flowview, see the attached picture. After clicking ok to this, cube material is not visible anymore in the 3D Editor and Material Editor & Browser do not show the cube's material. Switching between Edit Mode and Design Mode seems to update 3D Editor and show material in material editor & browser.
