I recommend you to try the following:

1. Select Tools-Options-Set default settings
   
2. Restart RoboDK
   

If the previous steps didn't help:
Do you have an old graphics card?
你试着更新图形卡驱动程序吗?
Can you run RoboDK by double clicking one of these files?

• C:/RoboDK/RoboDK-Safe-Start.bat
  
• C:/RoboDK/RoboDK-Safe-Start-VM.bat
  

To debug this issue better it would help us if you can follow these steps:

1. Close RoboDK
   
2. Start RoboDK by double clicking the file:
   C:/RoboDK/RoboDK-Debug.bat
   
3. Try to reproduce the problem in RoboDK until it crashes.
   
4. Right after the crash, provide us with this file:
   C:/RoboDK/bin/RoboDK.debug.txt
