TOP BAR SHOWING "NOT FOUND"

I have exactly the same issue :
 

Hey everyone,

Can you please try clearing your cache, force-quit the Figma Desktop app and restart it to see if that helps?
 
You can clear the desktop app cache on Windows under the toggle-arrow at the right of the top toolbar under Help > Troubleshooting. If you'd prefer to manually clear your cache you can:

1. Close the Figma desktop app
2. Open the Start menu, and paste in this, followed by enter: %APPDATA%\Figma
3. In the window that opens, delete the Desktop and DesktopProfile folders if they exist
4. Launch the desktop app again

 
You can clear the desktop app cache on a Mac in the Help menu under Troubleshooting. If you'd prefer to manually clear your cache you can:

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

If the issue still persists after clearing out the cache, I’d recommend you to reach out directly to our support team by filling this form: Submit a bug report
When contacting our support team, please use your Figma email account, mention the step you have done, and share your desktop OS. This will help us to investigate further: Thank you!
