Checking out from github on Windows has strange CRLF effect

Question

I am working on a project on two different Windows systems.

If I keep working on one system, git diff will correctly show the differences to the last commit. I commit my changes and push them to github.

But as soon as I want to continue on the other system, after a git pull origin main from github, and changing the code, git diff shows additional CR characters for line endings that I cannot explain other than it seems to happen only when github is involved.

The core.autocrlf config settings are false on both systems for the project, the user, and the system config. I use Visual Studio Code on both ends and the CRLF settings are equal in both editors.

What can I do to stop the erroneous behavior of git diff in this situation?

The comment regarding .gitattributes was worth its weight in gold :-)

I added the following to .gitattributes, committed it, pushed it, pulled it on the other side ... and now both sides no longer show weird git diff output

* text=auto
*.js text eol=crlf
