Cura 4.3 does not respond right after opening up

[broktion20 0]

cura goes into "not responding mode" right after opening it up. 

 

I had cura 3.x and tried to multiply model a black little rectangle also appeared and then it went into no responding mode. Then I restarted the software (3x version): no help, then I restarted the computer: no help. then I completely uninstalled cura 3.x and reinstalled 4.3 and it still goes into no responding mode right after I double click shortcut. 

I tried upgrading my intel graphics card driver however it is updated. 

I tried running the cura with my dedicated graphics card and in 3.8GHz clocking speed and it still goes into not responding. 

 

what is going on and what should I do to fix this?

I have similar problem, Cura 4.3 will not start after install - no idea what the problem is - does anyone have an idea?  Is it a recent Win10 update?
