Rider 2024.2.4 - How to exclude very large file from syntax highlighting?

On former version, Rider automatically excludes very large file from syntax highlighting.

On Rider 2024.2.4, When I opened very large file, Rider consumes very high CPU and memory and freeze because Rider does not exclude it from syntax highlighting.

I remember that Rider had maximum lines setting to exclude from it, but it was gone on 2024.2.4. 

Where is maximum lines setting?
