Continuously changing configurations and restarting the node caused the node to panic during runtime.

[sdjasj]

System information

Geth
Version: 1.13.15-stable
Git Commit: c5ba367
Git Commit Date: 20240417
Architecture: amd64
Go Version: go1.22.3
Operating System: linux
OS & Version: Ubuntu 22.04.3 LTS

Expected behaviour

After changing configurations, the node should not panic; at the very least, it should provide a friendly message to the user before panicking.

Actual behaviour

I repeatedly modified the configuration file and restarted the node. During one of the restarts, the node panicked at runtime. Below are the logs and error code from the node when the panic occurred.

Steps to reproduce the behaviour

I saved the node configuration file from when the panic occurred and attempted to reproduce the issue, but was unable to do so. However, the panic did indeed happen.

Thanks for submitting this issue, the problem is that the Lstat fails with an error that we did not handle correctly, I created a PR to fix it
