I made a list about all the errors message I got at the opening (BUILD 2.0.24_jyz) . I'm posting them here just below in their display order. There is a total of 10 spawns before it stop :
1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
I don't know if all of the windows calls can help you to track all bugs in your build but just in case. I'm doing this.
