Hello and welcome in the forum.
I don’t have this problem: view about 1 minute without problem. But I didn’t update Netflix often: my version is 8.75.0 build 6 50446 and the package is this: com.netflix.mediaclient.
I’m on eOS v. 1.12.3-s-20230615299639-stable-FP4.
You could try to clear cache and storage (you will lose your password accout and the next time you will have to rewrite it).
