I can't see people I working with in the design files

I have the same problem since 1 week…

Hi there! Welcome to the community and sorry to hear this is happening!
Is this happening on desktop app, browser or both? Do you see any error message? And, does this issue happens to a specific file or any files?

As a first step to troubleshoot, can you force-quit in your browser and/or desktop app. And, clear out your cache in browser and/or desktop app?

• You can follow the steps for the browser in this article: here

• And in the desktop app:
  Mac
  Use the Terminal app to clear the cache.

1. Quit the Figma desktop app.
2. Open the Terminal.app and enter the following command: rm -rf "$HOME/Library/Application Support/Figma/"{Desktop,DesktopProfile}
3. Try opening the Figma desktop app again.

Windows

Run a command line from the Start menu.

1. Close the Figma desktop app.
2. Open the Start menu and paste the %APPDATA%\\Figma command. Press the Enter key to submit.
3. In the window, delete the DesktopProfile folder.
4. Launch the Figma desktop app again.
