Yes, I have this too. On a 8gb pi 4, the 1.5.4 image works but running the update leads to no interface. I can still shh onto the pi, although this is not so helpful out in the field.
I've got the same problem here. Just bought Stellarmate OS 1.5.4 and installed on my Raspberry Pi 8GB with a 128GB SD card. I can get it to boot initially, but can't connect or get response after update.
I also tried booting from USB 3.0, but for some reason the wifi won't work when I boot from the USB, so I can't connect with the app, VNC, etc.
It worked! I downloaded a fresh copy of 1.5.4, and it worked fine. Thanks! I used the Software Update tool this rime. Last time I did the update from the command line using the apt-get update and apt-get upgrade. I doubt that made any difference, though.
Also, I tried to boot from a USB 3 thumb drive again. It boots, but the wifi still doesn't work (in either hot spot mode or connection to local wifi). I wonder if the the thumb drive is causing 2.4GHz interference? I may try a SSD or external USB wifi antenna to see if those will work. The USB boot isn't a deal breaker for me, just something I would like to do eventually.
