Major INDI Library release v1.9.0 bring significant internal changes championed by @pawel-soja to modernize core INDI Library drivers and clients. New drivers for DeepSkyDad Flat Panel & Pegasus devices plus further improvements to PCM8 drivers.
You need to update the bootloader, there is a new firmware update as of the 9/9/2020...I did not have this and so all sorted now...
Stellarmate OS on Raspberry pi4b
Skywatcher EQ8 pro, on steel pier
Takahashi FSQ85, FS60cb & Meade 8” SCT (de-forked)
Starlight Xpress SXVR H18, SXVR M25c, Lodestar x2 Guide Camera
Pegasus Ultimate Hub V2 for all USB & Power
Pegasus focus motors on all scopes
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.

I bought StellarMate in 2018. This week I downloaded the image. Using my trusted method of building an image, I created the image on a 400G drive. My first try failed. I viewed the image and only AstroBerry folder was present. My second try produced the obligatory “this drive is no longer formatted” in Windows 10 version 2004. Maybe I zigged when I should have zagged. The AstroBerry empty folder was it.
The third try I did not format the drive. I placed the image over the previous session. This went much faster. I then used my RPI3B+ with Ubuntu to fsck the volume. Sure enough, the volume had a dirty bit. Hmm... I ejected the Volume from Windows. I umounted the volume under Ubuntu. Why the dirty bit? Looks like either the image tool or the image has a dirty bit.
Once the dirty bit was repaired, the volume booted fine. I am now running on StellarMate.
