Netflix Settings Flickering

Bug
1

I opened the series, and it was in Japanese by default. I am experiencing a video (settings) flickering issue while trying to change Dub and Sub (I tried in Mushoku Tensei).

I have changed to these:
Netflix subtitle language : ASR Deutsch
Netflix audio language : Deutsch

After making these changes, the system automatically switches the language back to Japanese and then returns to Deutsch 2 to 3 times per second continuously. Due to this endless loop, the video does not play at all. I can upload a video if its needed (but where?)

I found a temporary workaround, to stop the flickering by using the native Netflix player menu (while LR is still active) rather than the LR gear button.

I changed the audio language to “Deutsch” using the Netflix UI. The flickering continued at first. I repeatedly clicked on “Deutsch” in the Dub selection multiple times until the flickering finally stopped.
After that, I selected “ASR Deutsch” in the Netflix subtitle menu and repeatedly clicked it as well until the flickering stopped.
