Error browsing /etc

Using the GUI interface, on 5.13.1 (Build 8265), both Explorer and Commander style, when viewing this particular directory /etc/config, I get the following error:

Unexpected directory listing line 'drwxr-xr-x 1 root root 18446744073709551568 Apr 18 14:38 config'.

I've attached the log. It seems the option --full-time is the issue.

It's rather the non-sense size 18446744073709551568.
Your file system seems corrupted.
