cannot open files

[BETLOG]

This began when a fluidd GUI 'update all' was interrupted by running out of disk space.
Config, logs, example configs and gcode are now unviewable.

Files are editable via ssh, and a cursory check of permissions looks normal:
2024-05-17_fileAccess.zip
2024417-181138.zip

Even after installing a new, preflashed 32GB EMMC the problem persists.
Unfortunately I forgot to check if the file editing issue existed before I did a full update of fluidd/klipper etc, and copied my printer.cfg to the host. So I dont know for sure that it is the update, or my config that breaks it. As far as I remember I havent changed by configs for several weeks, and they look normal to me, so I'm thinking its an update problem.

The printer otherwise prints, and the fluidd GUI functions as normal.
but:
I cannot save endstop adjustments made on the klipperscreen...
I can save zprobe adjustments made on the klipperscreen.

I only got one potentially useful error prior to switching in the new EMMC but I cannot reproduce it now, despite still not being able to view/edit any file.
Note regarding the logs included here:

1. I reboot the printer host (MKS SKIPR, integrated Host and MCU board),
2. and then clicked, one by one, all configs in the left panel, and all logs in the right, and none of them open. AFAIK the logs do not show any evidence of this.
