I did not delete the file but deleted the line in the known_hosts file. I hope that’s fine.

I AM now able to ssh into my umbrel. Look forward to running some commands to fix my ssd missing and system service failure errors! Thank you.

If you know how to use a computer, you also know how to delete a file in C://Users/user_name/.ssh/known_hosts
If you do not know how to delete a temporary file, not sure if you really will be able to maintain a node. Sorry.
