Error on Theme Editor

Hello Guys!

There is a strange error on my back end when I’m using plugin version greater than 4.4.9.
On Theme Editor the names of the files do not appear in Human Readable format. So instead of “Main Index Template”, I’m receiving just “index.php”. And it’s occuring in all files with Human Readable format, such as: “Header, footer, etc”.

I’m using a custom theme, based on the Underscore theme: https://underscores.me/
This error, is being occuring since WordPress 5.0.
I’m now using php 8.0 and the WordPress 6.1.

… Version 4.4.9 (No issues)

… Greater versions (Error)

Any clue how to fix that?
