The program is stuck at the last step

[hlyyy]

Hi! I encountered a problem in the last step. I hope you can help me.

When I Start Apollo and LGSVL in the last step, I got the following results, I found that the execution would get stuck at this point. After waiting for a long time, there was no result and no error was reported. Dreamview and LGSVL also don't respond:

I'm sure I followed the readme, but I don't know what went wrong. Are there any additional steps that I didn't do?

If you have time to help solve my problem, I would be very grateful!
