Assistance Needed - Raspberry Pi4 Black Screen After Service Configuration

[yizhiweimengxiangfendoudefeifei]

After flashing the image to my SD card and enabling the following services:
“sudo systemctl enable wifibroadcast@gs
sudo systemctl enable rtsp
sudo systemctl enable fpv-video
sudo systemctl enable osd ”
my Raspberry Pi4b fails to boot properly. Upon rebooting (sudo reboot), the screen remains black with no display output. Could you please help diagnose this issue? I'd appreciate any guidance.

Thanks!

Hi, do SSH, i get some messages as follows:

[svpcom]

wfb-ng service starup has been failed.
See sudo journalctl -xu wifibroadcast@gs

[yizhiweimengxiangfendoudefeifei]

hello, i got another error, when i write "ifconfig", it shows:

but i open log, find it error "Cannot find device "wlan0"", can you help me? Thanks a lot.

May be you have a race between wlan0 initialization and wfb-ng start. Try to restart wifibroadcast@gs service manually after you ensure that wlan0 is up

Hello again,

I previously solved an issue with your help—thank you! I’ve been using wfb-ng successfully on a Raspberry Pi 4B. However, I’ve encountered a new problem after switching to a Raspberry Pi Zero.The system freezes as follows, using wfb-ng's version 23.01. Could you help me troubleshoot this? Let me know if you need more information. Thanks in advance!
