Error: system service failed

I think this may be my problem as well. I am getting Failed to start External Storage SDcard Updater.
my Umbrel stopped responding during an upgrade to the latest version. so this must be it. how do I stop it from checking to “update”. My problem is, I tried using SSH, but I dont know my umbrel logins password. I thought I changed it from the default password, but neither seem to work. if I take out the micro SDcard, and insert it to a different pc, would I be able to access the needed files?

EDIT:
Using Putty, I was able to SSH into the node, however I had to use the default password, from there I ran: “rm -f ~/umbrel/statuses/update-in-progress && sudo reboot”
after the restart, I am now able to make it to dashboard
