Was she usually more present in TV productions or more in film? Because it makes a difference, since sometimes actors shift their focus without completely disappearing from screens.
What I can say is that artists from her generation have been diversifying quite a bit - some get into podcasts, content for streaming platforms that isn't as visible as a series on open TV, or simply take on more selective projects. This can look like a disappearance when it's really just a change in strategy. Besides, there are natural periods when someone drops off the radar because of personal projects or just because work is moving slower - the industry isn't linear.
The best way really is her social media, but you can also take a look at platforms like IMDb or Letterboxd to see if she has something in post-production or confirmed for soon. Sometimes projects exist but haven't been publicly announced yet, especially if they're for international streamers that take longer between filming and release.
