can't get wyze running on two V3 but working on the rest

[eng3]

I've been running wz_mini_hacks on several V3 for about a year. A few stopped working entirely (even without the card inserted) so I replaced them. I went through the wyze setup process and can view video. I checked the firmware and they are all at 4.36.9.139. For two of them, I plugged in the old card and its working fine. For the other two, it didnt work. I checked the card and it seems the card died too as I can't read the cards or I cant can't format it.
So I bought new cards, formatted them FAT32, ensured MBR. Copy the SDCARD folder.
wz_mini.conf modifications are just hostname, and turning on go2rtc and disabling night drop.
It still doesnt work. I can see the video using the wyze app. I can't ping the IP and I cant connect to the go2rtc web interface (no response) or get video.
Any suggestions on what else to try?

I can't ping the IP
How is Wyze accessing them? (I haven't used the wyze app in years) but they need an ip address on some network (internal or the internet) and ping works even without wz_mini_hacks installed.

Step 1 is to figure out the IP address of the cameras

I know my camera's IP address, otherewise I wouldn't have been able to try to ping it.
Anyways, I resolved the issue. Apparently I had two bad SD cards.
