What is the name of this film? Pink illuminated window, villa, computer game, gaming, VR, psycho, thriller, drug addict, parallel worlds, sci-fi, San Francisco?

I'm looking for the title of a movie that I saw on Netflix about 2 years ago. Maybe it was also an episode of a sci-fi series. I can remember the following from the story - pretty crazy when I reproduce it with gaps (and possibly not quite correctly), but I found the film itself really good:

It felt like the whole time about a house, a villa that had a pink / pink illuminated window above. The aim of the main characters (I mean a girl, see below and two commissioners) was to get into the room with this window.

The villa was very shabby and somehow also a nest for drug addicts. But at the same time they tested a new virtual reality computer game or social media network or something.

When you were in the villa, different worlds opened up, so it could be that she was part of the VR: Sometimes the villa is completely renovated, sometimes all the rooms are on fire, sometimes there's a model of the villa in the pink room, sometimes the whole villa is just a backdrop for a film…

Then about the girl mentioned above, one of the main actors: she is also a tester for the VR game and probably super good at it. She solves puzzles that others don't solve and that inspires, even the head of the VR company, so that he recruits her for testing (she meets with him at the sea and she sees something that he has programmed into the game that others don't see) … Uh, kind of like…

I also think that the film is set in San Francisco.

Sounds a bit like the series "the OA"

Ha, yes, that was it… The pink rose window from the second season! A heartfelt thank you!
