I can confirm you are on a Rasperry Pi 4 or a Linux setup? Is your Umbrel accessible at all currently, you can reach its dashboard? Also to confirm, are you able to open your Bitcoin Node app and it is blank or is it stuck on “Starting?”
Can you also please provide your debug log? You can generate it via System > Troubleshoot > Start and upload the log file here. Or if you can’t reach the dashboard, steps on how to SSH and generate the debug log are here: Official Umbrel Troubleshooting Guide and FAQ
If you print the log via the command line you can copy and paste a link from here to share it http://www.pastebin.com for easier review if you don’t want to paste the whole log right onto the forum.
Happy to review and further troubleshoot
