New to Arch-based - issue with latest iso

Apologies, I did not see that it cut off some of the data after copy pastaing. It should have all data now in the original post.

Output for the other commands requested.

mmcblk0 is the internal storage of the SurfaceGo
mmcblk1 is the external SanDisk uSD card

Just FYI on the sd/mmc disks.

Update: I got it to format when using the USB-C port. Showed up as SDA instead of mmcblk1 when using a uSD usb reader.

uSD works now. Needed a workaround and still irks me that the built in uSD slot doesn’t work to format it. At this moment, however, everything, that is essential to work with it, is working.

EDIT: spoke too soon. rebooted and same issue as before…

EDIT2: I tried a couple of uSD cards last night to test to make sure that the card reader was not the issue. Turns out that it has something to do with specifically SDXC cards. A 256MB (SD) and a 16GB (SDHC) uSD worked perfectly fine, multiple reboots.
